森林里的蘑菇对比英语作文The Enchanting Fungi of the Forest: A Comparative Analysis.Within the verdant embrace of the forest, wherenature's artistry unfolds in its myriad forms, there exists a realm of wonder and intrigue: the realm of fungi. These enigmatic organisms, neither plant nor animal, have captivated human imagination for centuries, inspiring both awe and curiosity. Two such fungi, the solitary Fly Agaric and the communal Honey Mushroom, offer a fascinating case study of the diversity and ecological importance of this remarkable kingdom.Fly Agaric: The Solitary Sentinel.Amanita muscaria, commonly known as the Fly Agaric, stands out as a solitary beacon of beauty amidst theforest's mosaic of life. Its brilliant red cap, adorned with distinctive white spots, serves as a vibrant warningto potential predators. Beneath the cap lies a pure white stem, which rises majestically from the forest floor.Fly Agaric is a mycorrhizal fungus, forming symbiotic relationships with the roots of trees, particularly thoseof birch. This mutually beneficial partnership allows the exchange of nutrients between the two organisms. In return for sugars provided by the tree, the fungus aids in the absorption of water and minerals from the soil, enhancing the tree's overall health and resilience.Despite its alluring appearance, Fly Agaric is a potent hallucinogen, containing psychoactive compounds that have been used for shamanic and medicinal purposes for centuries. Its effects range from euphoria to visual hallucinations, but its consumption can also be dangerous, causing nausea, vomiting, and even organ failure.Honey Mushroom: The Communal Empire.In contrast to the solitary nature of Fly Agaric, Honey Mushrooms, belonging to the genus Armillaria, form vastunderground networks that connect individual mushrooms across extensive distances. These networks, known as mycelia, spread through the soil in search of nutrients, colonizing tree roots and forming the foundation of complex underground ecosystems.Honey Mushrooms are saprobic fungi, deriving their sustenance from decomposing organic matter. Their presence accelerates the decomposition process, releasing nutrients back into the soil and contributing to the forest's ecological balance. They favor moist, shady environments, often congregating in large clusters around the base of trees.The Honey Mushroom's communal nature has significant ecological implications. By sharing resources and coordinating their activities, the network can efficiently exploit available food sources and withstand environmental stresses. This cooperation also allows them to spread rapidly through the forest, effectively colonizing new areas and establishing new colonies.Ecological Significance of Fungi.Both Fly Agaric and Honey Mushrooms play crucial roles in the delicate equilibrium of the forest ecosystem. Their mycorrhizal and saprobic activities contribute to nutrient cycling, soil health, and the decomposition of organic matter. By creating and maintaining underground networks, fungi facilitate communication and nutrient exchange among plants and other organisms, fostering interconnectedness and resilience within the forest community.Moreover, fungi provide a valuable food source for various animals, including insects, rodents, and larger mammals. Their role in nutrient cycling also impacts the availability of food for other organisms in the food chain, including herbivores and predators. The intricate web of relationships between fungi and other forest inhabitants further emphasizes the interconnectedness and interdependence of life within the ecosystem.Conclusion.The Fly Agaric and Honey Mushroom, though vastly different in their solitary and communal lifestyles, exemplify the remarkable diversity and ecological importance of fungi in the forest. Their unique adaptations and interactions with other organisms contribute significantly to the intricate balance and resilience of this vibrant ecosystem.As we delve deeper into the realm of fungi, we uncover a hidden world of complexity and beauty. From the mesmerizing colors of Fly Agaric to the subterranean empires of Honey Mushrooms, these enigmatic organisms remind us of the interconnectedness of life and the vital role that each species plays in the symphony of nature.。

两个物种区别英语作文The Distinctions between Elephants and GiraffesWhen we think about the animal kingdom, two remarkable species that often capture our attention are elephants and giraffes. Despite both being large and fascinating creatures, they have numerous distinct characteristics.One of the most obvious differences lies in their physical appearance. Elephants are known for their massive size, with thick, sturdy legs and a long trunk. Their large ears flap like fans, and they have a thick, wrinkled skin. In contrast, giraffes have extremely long necks and legs, which enable them to reach the highest branches for food. Their coat patterns are unique and often serve as a form of camouflage.The way they move is also quite different. Elephants walk with a slow and heavy gt, due to their considerable weight. Giraffes, on the other hand, have a more graceful and cautious stride, given their height and the need to balance.In terms of diet, elephants are mnly herbivores, consuming a wide variety of plants, roots, and bark. Giraffes, with their long necks, specialize in feeding on the leaves of tall trees.Another significant distinction is their social behavior. Elephants are highly social animals, living in close-knit family groups led a matriarch. Giraffes, while not as tightly organized in family units, still have social interactions among themselves.The habitats in which they thrive also vary. Elephants can be found in a range of environments including forests, grasslands, and deserts. Giraffes are typically associated with savannas and open woodlands.In conclusion, although both elephants and giraffes are remarkable in their own ways, their differences in appearance, movement, diet, social behavior, and habitat make them unique and fascinating species in the animal world.。

小学英语作文-Differences Between Plants and Animals 植物和动物之间的差异
小学英语作文:Differences Between Plants and Animals 植物和动物之间的差异Differences Between Plants and AnimalsThere are several characteristics which distinguish plants from animals.Generally speaking, plants are able to manufacture their own food, by using substances in the environment through the process which is known as photosynthesis. They can grow very well if they have enough sunshine, rainfall and fertilizer. In contrast, all animals, including man, get their food either directly from the plants or indirectly by eating animals which feed on plants or other animals. Animals, therefore, need a wide range of food than plants.Plants are stationary. They do not have the power to move. Animals, on the other hand, can usually move about. Consequently, plants appear to be less sensitive then animals although they respond in some ways to light, heat, physical contact and other stimuli.Plants are usually green. Animals, however are very diverse in external appearance. They may appear in any color you can think of.[点评]这篇描述文用对比的方法对植物与动物之间的不同点逐一作了描述。

plantsandanimals作文
plantsandanimals作文英文版Plants and AnimalsPlants and animals are two essential components of our ecosystem. They coexist and interact with each other in a complex web of life, maintaining the balance of nature.Plants are the foundation of the food chain. They absorb sunlight, water, and carbon dioxide from the atmosphere and convert them into oxygen and glucose through the process of photosynthesis. This glucose is then used by plants as energy and also serves as a source of food for animals. Animals consume plants directly or indirectly, thus completing the food chain.Animals, on the other hand, play crucial roles in the ecosystem. They help in the dispersion of seeds, pollination, and nutrient cycling. Some animals feed on pests, thus controlling their population and preventing them from causing harm toplants. Others, like herbivores, graze on plants, helping in their growth and maintaining the health of the grassland ecosystem.However, the relationship between plants and animals is not always harmonious. Sometimes, plants produce toxins to defend themselves against herbivores. Similarly, animals have evolved to develop resistance against these toxins, allowing them to feed on these plants. This co-evolutionary process has led to the diversity of species we see today.In conclusion, plants and animals are intertwined with each other in a delicate balance of nature. Their coexistence and interaction are crucial for maintaining the health and stability of our ecosystem. It is important for us to appreciate and respect this symbiotic relationship and do our part to conserve and protect the biodiversity of our planet.中文版植物与动物植物和动物是我们生态系统的两个基本组成部分。

这张图比较了动物种群的趋势英语作文Title: Analyzing the Trends of Animal Populations: A Comparative InsightIn the intricate tapestry of our planet's biodiversity, animal populations serve as vital threads, weaving together the fabric of ecosystems. The rise and fall of these populations reflect the delicate balance between survival and extinction, a dynamic that is increasingly influenced by human activities. This essay delves into a comparative analysis of animal population trends, highlighting patterns, underlying causes, and the implications for both wildlife conservation and our shared future.IntroductionThe world is witnessing an unprecedented rate of species decline, with many animal populations facing severe threats. From the majestic elephants of Africa to the elusive pandas of China, these creatures serve as bellwethers of environmental health. By examining the trends of diverse animal populations, we can gain valuable insights into the health of our planet and the urgent need for conservation measures.Trends in Animal PopulationsDeclining Populations: A pervasive trend is the steep decline in numerous animal species. For instance, the tiger population has plummeted from an estimated 100,000 individuals in the early 20th century to around 4,000 today, primarily due to habitat loss, poaching, and human-wildlife conflict. Similarly, the vaquita, a critically endangered porpoise found only in Mexico's Gulf of California, is on the brink of extinction with fewer than 10 individuals left in the wild. Recovering Populations: Amidst the gloom, there are also heartening stories of recovery. The gray wolf, once hunted to near-extinction across much of its range, has made remarkable strides towards recovery in some regions, thanks to rigorous conservation efforts and reintroduction programs. Similarly, the giant panda, once classified as endangered, has seen its population stabilize and even increase due to conservation efforts and improved habitat management.Stable Populations: Some animal species maintain relatively stable populations, often the result of effective management strategies and sustainable practices. Examples include certain bird species in well-protected national parks and wildlife reserves, where balanced ecosystems and minimal human disturbance allow for natural population fluctuations within healthy limits.Underlying CausesThe drivers behind these varying trends are complex and multifaceted. Habitat loss and fragmentation, caused by deforestation, urbanization, and agricultural expansion, top the list of threats. Climate change, with its erratic weather patterns and shifting habitats, exacerbates these issues. Additionally, overexploitation through hunting, fishing, and poaching, as well as pollution and the introduction of invasive species, contribute significantly to population declines. Implications and SolutionsThe declining trends of animal populations have far-reaching implications, threatening ecosystem services upon which humans depend, such as pollination, pest control, and climate regulation. To reverse these trends, a multi-pronged approach is necessary. This includes:Strengthening Protected Areas: Establishing and expanding protected areas, ensuring they are effectively managed and adequately funded, is crucial for safeguarding habitats and preventing further habitat loss.Sustainable Resource Management: Promoting sustainable land use practices and responsible wildlife trade can reduce pressure on animal populations.Climate Action: Addressing climate change through mitigation and adaptation efforts is vital to preserving habitats and supporting species resilience.Public Awareness and Education: Raising awareness about the importance of biodiversity conservation and encouraging community involvement in conservation efforts can foster a sense of stewardship towards nature.International Cooperation: Given the global nature of many wildlife threats, international cooperation and collaboration among governments, NGOs, and local communities is essential for effective conservation.ConclusionThe trends in animal populations serve as a stark reminder of the fragility of our planet's biodiversity and the urgent need for action. By understanding the underlying causes, implementing targeted solutions, and fostering a collective commitment to conservation, we can work towards reversing these trends and securing a future where all species, including our own, can thrive. The time for action is now.。
plantsandanimals作文
plantsandanimals作文英文版Plants and AnimalsPlants and animals are two integral parts of our ecosystem. They co-exist and interact with each other in a complex web of life, forming the foundation of our planet's biodiversity.Plants are the primary producers in the food chain. They absorb sunlight, water, and carbon dioxide to produce food through photosynthesis. This process not only sustains them but also provides energy and nutrients to animals through the food chain. Without plants, the majority of animals would not have a reliable source of food.Animals, on the other hand, play crucial roles in the ecosystem. They consume plants and other animals, thus controlling their population growth and maintaining a balance in the ecosystem. Some animals, such as bees, also assist inplant reproduction by pollinating flowers. Others, like elephants, create habitats for other species by dispersing seeds.The relationship between plants and animals is not always harmonious, however. Some animals feed on plants to obtain nutrients, while others may damage them for various reasons. Plants, in turn, have developed various defense mechanisms to protect themselves from predators.Despite these interactions, both plants and animals are facing numerous threats today. Habitat loss, pollution, climate change, and invasive species are just a few of the factors that are threatening their survival. It is crucial that we take action to protect and conserve these species to ensure the health and diversity of our planet's ecosystem.中文版植物与动物植物和动物是我们生态系统中的两个重要组成部分。
两种动物对比的英语作文
两种动物对比的英语作文英文回答：The animal kingdom is a vast and diverse realm, teeming with an astonishing array of creatures. From the microscopic to the colossal, each species possesses unique characteristics and adaptations that have evolved over millions of years. In this essay, we will delve into the intriguing world of two extraordinary animals: the majestic lion and the enigmatic wolf.Physical Attributes.Lions, belonging to the Panthera genus, are renownedfor their imposing physiques. Adult males typically weigh between 400 and 550 pounds, while females are significantly smaller, weighing 250 to 350 pounds. Their most distinctive feature is their luxurious mane, which frames their face and provides protection during confrontations. Wolves, on the other hand, belong to the Canis genus and arecharacterized by their lean and muscular bodies. Malewolves can weigh up to 120 pounds, while females typically weigh less than 90 pounds. Wolves possess a thick, double-layered coat that insulates them against harsh weather conditions.Habitat and Distribution.Lions are primarily found in sub-Saharan Africa and a small portion of southern Asia. They prefer open grasslands, savannas, and woodland areas. Wolves, on the other hand, have a much wider distribution, ranging from the Arctic tundra to the lush forests of North America and Eurasia. They are highly adaptable and can thrive in various habitats, including mountains, deserts, and swamps.Social Structure and Behavior.Lions exhibit a complex social structure, formingprides consisting of multiple related individuals. Prides typically consist of one or two dominant males, several females, and their offspring. Males play a protective role,defending the pride's territory and hunting for food. Females are responsible for raising and nursing the cubs. Wolves also live in social groups known as packs. Packs are usually smaller than lion prides, consisting of a breeding pair, their offspring, and other related individuals. Packs are hierarchical, with the alpha pair maintaining dominance.Hunting and Feeding.Lions are apex predators, occupying the top of the food chain in their ecosystem. They are skilled ambush hunters, using their powerful muscles and sharp claws to bring down large prey such as zebras, wildebeest, and antelope. Wolves are also predators, but they typically target smaller prey such as deer, elk, and rabbits. They employ cooperative hunting strategies, working together to outmaneuver and subdue their quarry.Conservation Status.Both lions and wolves face significant conservation challenges. Lions are listed as "vulnerable" on theInternational Union for Conservation of Nature (IUCN) Red List, primarily due to habitat loss, poaching, and human-wildlife conflict. Wolves are also facing population declines, primarily due to hunting, habitat destruction,and disease. Conservation efforts are underway to protect these magnificent creatures and ensure their survival.中文回答：狮子和狼的对比。
英语动物对比的作文
英语动物对比的作文Animals are an integral part of our world, and they come in all shapes and sizes. From the majestic lion to the tiny ant, the animal kingdom is diverse and fascinating. In this essay, I will compare and contrast various English animals from different perspectives, including theirphysical characteristics, behavior, and their roles in the ecosystem.First and foremost, let's take a look at the physical characteristics of some iconic English animals. The red fox, for example, is known for its bushy tail, pointed ears, and sleek, reddish-brown fur. In contrast, the badger has a stocky build, with a black and white striped face and powerful claws for digging. Moving on to birds, the robin has a distinctive red breast and a melodious song, whilethe majestic swan is known for its long, graceful neck and pure white feathers. These physical differences not only make each animal unique but also serve specific purposes in their survival and daily activities.In terms of behavior, English animals exhibit a wide range of traits that set them apart from one another. For instance, the red fox is a cunning and resourceful hunter, often seen stalking its prey with stealth and agility. On the other hand, badgers are more solitary creatures, preferring to live in underground burrows and forage for food at night. When it comes to birds, the robin is knownfor its bold and inquisitive nature, often approaching humans for food, while swans are more elegant and serene, gliding gracefully across the water. These behavioral differences reflect the unique adaptations of each animalto its environment and lifestyle.Furthermore, the roles of English animals in the ecosystem are crucial for maintaining the balance of nature. Foxes, for example, play a vital role in controlling the population of small mammals such as rabbits and rodents, thus preventing overgrazing and the spread of disease. Similarly, badgers are important for aerating the soil and controlling insect populations through their digging and foraging activities. Birds like the robin and swan alsocontribute to the ecosystem by dispersing seeds,controlling insect populations, and adding to the overall biodiversity of their habitats. Without these animals, the delicate balance of the ecosystem would be disrupted, leading to potential negative consequences for otherspecies and the environment as a whole.In addition to their physical characteristics, behavior, and ecological roles, English animals also hold a special place in the hearts of people. Many individuals have a deep emotional connection with these animals, whether through personal encounters in the wild or through cultural and literary associations.

Similarly, the badgerhas been revered in literature and folklore for itstenacity and resilience. Birds like the robin and swan are also celebrated in art, music, and poetry for their beauty and symbolism. These emotional connections reflect the enduring appeal of English animals and their significancein human culture and imagination.In conclusion, English animals are diverse and fascinating creatures with distinct physical characteristics, behavior, and ecological roles. From the cunning fox to the serene swan, each animal brings its own unique qualities to the natural world. By understanding and appreciating these differences, we can gain a deeper appreciation for the rich tapestry of life that surrounds us and work towards preserving and protecting the precious wildlife that enriches our planet.。
动物对比英文作文开头
动物对比英文作文开头英文：When it comes to comparing animals, there are many ways to approach the topic. Some people might focus on physical characteristics, while others might look at behavior or habitat. Personally, I think one interesting way to compare animals is by their intelligence.Some animals are known for their high level of intelligence, such as dolphins, chimpanzees, and elephants. These animals have been observed using tools, communicating with each other, and even showing empathy towards members of their own species. On the other hand, there are animals that are not as known for their intelligence, such as insects or reptiles.However, it's important to remember that intelligence can be difficult to measure and compare across different species. What might be considered intelligent behavior inone animal might not be the same in another. For example, a spider might not be able to use tools or communicate with other spiders, but it is still able to build intricate webs and catch prey.中文：当涉及到比较动物时，有许多方法可以处理这个话题。

Animal Experimentation
Summary:Is it morally acceptable to experiment on non-human animals to develop products and medicines that benefit human beings?
Animals have the right to be treated as beings of value in themselves, not as the means to human ends; this principle must be applies in order to guarantee the end of cruelty to animals. The application of this principle means that animals should never be experimented upon whatever the potential gain for humanity. To infect monkeys with the AIDS virus or to expose rodents to toxic chemicals and radiation is simply not acceptable, whatever the supposed benefits.
Artificial Plants and Real Plants 大学英语对比作文
Artificial Plants and Real PlantsArtificial plants have more advantages than real plants in many ways. Artificial plants have a long history. According to legend, early in Tang Dynasty, in order to attract the emperor’s attention, some imperial concubines decorated themselves with artificial flowers when there were no real flowers in winter. These flowers were made by maids in the imperial palace from silk. Since artificial flowers are beautiful and can be kept for a long time, making artificial flowers and plants became more and more popular among common people. As time goes by, the technology of artificial plants has been improving. At present, we can see that artificial plants are widely used in many occasions. In contrast to real plants, the advantages of artificial plants become obvious.Firstly, artificial plants are cheaper than real flowers. Artificial plants have lower prices because the costs of most raw materials and labor are low, and the competition in this field is quite fierce. The competition attributes to the more demanding requirements from consumers and the rapid development of technology. Consumers ask more various, beautiful, vivid artificial plants and the improving technology urges producers develop new products. Thanks to these conditions, the prices of artificial plants are cheap. When it comes to real plants, although the competition is fierce, the money and time to plant and take care of them couldn’t be ignored. Therefore, it’s no doubt that the real plants are more expensivethan the artificial ones.Secondly, artificial plants can keep its original shape for a long time. None of them are affected by the exchange of four seasons because they are made of various synthetic materials. It means that artificial plants are always beautiful. As we all know, trees would grow, get illness, lose leaves and die, flowers would blaze, peak and fade. Some people may enjoy this process, but in more cases, people need plants that can keep their best shape. For example, a manager plans to buy some plants to decorate his restaurant. He has to change the dead plants from time to time if he buy real plants. In order to achieve the best effects with the least payment, the manager would tend to choose artificial plants.Thirdly, it is more convenient to take care of artificial plants. It’s simple to look after them. On one hand, we must avoid them getting close to hot things and protect them from exposure to the sun. On the other hand, we just need to wash and dry them when they were covered with dust. However, it’s troublesome to bring up a real plant. A real plant need watering regularly, and deinsectization, weeding, fertilization according to its conditions. What’s more, if it is sick, its leaves would turn yellow, its flowers would fade. In that case, the plant might not be so ornamental. Generally speaking, real plants are suitable for leisure people but not busy people, because it takes man a lot of time to conserve a real plant. But everyone can take good care of an artificial one.Last but not least, artificial plants would not cause allergy. Many people around us are suffering from allergy, especially pollen allergy. For a woman who is allergic to pollen, it’s so regretful that she can’t decorate her house with flowers. But thanks to artificial plants, now she has another choice. Most artificial flowers’appearances and even fragrance are remarkably similar to real flowers’. She can closely appreciate those flowers without worries.People usually choose artificial plants in many occasions because they are cheaper, more convenient, safer and can maintain for a long time. However, real plants have to be used when people want to show their sincere desire. As a result, although artificial plants have a lot of advantages, it still depends on situations where artificial plants or real plants should be used.。

Comparing Plant And Animal Cells/video?v=Hmwvj9X4GNYPlant Cellsshape - most plant cells are squarish or rectangular in shape.amyloplast (starch storage organelle)- an organelle in some plant cells that stores starch. Amyloplasts are found in starchy plants like tubers and fruits.cell membrane - the thin layer of protein and fat that surrounds the cell, but is inside the cell wall. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others.cell wall - a thick, rigid membrane that surrounds a plant cell. This layer of cellulose fiber gives the cell most of its support and structure. The cell wall also bonds with other cell walls to form the structure of the plant.chloroplast - an elongated or disc-shaped organelle containing chlorophyll. Photosynthesis (in which energy from sunlight is converted into chemical energy - food) takes place in the chloroplasts. chlorophyll - chlorophyll is a molecule that can use light energy from sunlight to turn water and carbon dioxide gas into glucose and oxygen (i.e. photosynthesis). Chlorophyll is green.cytoplasm - the jellylike material outside the cell nucleus in which the organelles are located.Golgi body - (or the golgi apparatus or golgi complex) a flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus. The golgi body modifies, processes and packages proteins, lipids and carbohydrates into membrane-bound vesicles for "export" from the cell. lysosome - vesicles containing digestive enzymes. Where the digestion of cell nutrients takes place. mitochondrion - spherical to rod-shaped organelles with a double membrane. The inner membrane is infolded many times, forming a series of projections (called cristae). The mitochondrion converts the energy stored in glucose into ATP (adenosine triphosphate), a high energy molecule, for use by cell. nuclear membrane - the membrane that surrounds the nucleus.nucleolus - an organelle within the nucleus. Ribosomal RNA is produced here, then exported into the cytoplasm where it forms the ribosomes.nucleus - The nucleus is a spherical body surrounded by the nuclear membrane. It contains mostly DNA in chromosomes. The nucleus controls many of the functions of the cell (by controlling protein synthesis). The nucleolus is found within the nucleus.ribosome - small organelles composed of RNA. Are sites of protein synthesis.rough endoplasmic reticulum - (rough ER) a vast system of interconnected, membranous, infolded and convoluted sacks that are located in the cell's cytoplasm (the ER is continuous with the outer nuclear membrane). Rough ER is covered with ribosomes that give it a rough appearance. Rough ER transport materials and produces proteins (which are sent to the Golgi body, or inserted into the cell membrane).smooth endoplasmic reticulum - (smooth ER) a vast system of interconnected, membranous, infolded and convoluted tubes that are located in the cell's cytoplasm (the ER is continuous with the outer nuclear membrane). It produces lipids (fats) and membrane proteins; smooth ER buds off from rough ER, moving the newly-made proteins and lipids to the Golgi body for further processing and to the membranes.vacuole - a large, membrane-bound space within a plant cell that is filled with fluid, mostly water. Most plant cells have a single vacuole that takes up much of the cell. It helps maintain water balance and the shape of the cell.vesicle - a small, membrane-bound space that helps to transport material in/out or within the cell. Some are storage vessels. eg. proteins produced in the rough endoplasmic reticulum are transported by vesicles produced at the tips of the rough ER, to the golgi body, for processing.Animal Cellshape - most animals cells are roundish or irregular in shape.cell membrane - the thin layer of protein and fat that surrounds the cell. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others.centriole - during cell division in animal cells, two pairs of centrioles form from microtubules at each end of the cell. The two centrioles are arranged perpendicular to each other. Microtubules formed in the centriole grow into spindle fibers which then attach to replicated chromosomes and assist in separating them during mitosis.cytoplasm - the jellylike material outside the cell nucleus in which the organelles are located.Golgi body - (also called the golgi apparatus or golgi complex) a flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus. The golgi bodymodifies, processes and packages proteins, lipids and carbohydrates into membrane-bound vesicles for "export" from the cell.lysosome - vesicles containing digestive enzymes.

The vacuole fills with food being digested and waste material that is on its way out of the cell. Smaller than plant cell vacuole. vesicle - a small, membrane-bound space that helps to transport material in/out or within the cell. Some are storage vessels. eg. proteins produced in the rough endoplasmic reticulum are transported by vesicles produced at the tips of the rough ER, to the golgi body, for processing.Name________________Comparing Plant And Animal Cells VENN DiagramDirections: Fill in the VENN Diagram to compare PLANT CELLS to ANIMAL CELLS.
