英文回答：
The leaves of trees are both beautiful and essential. They come in a variety of shapes and sizes, and they can be found in every color of the rainbow. Leaves are responsible for photosynthesis, which is the process by which plants convert sunlight into energy. They also help to regulate
the temperature of the plant and provide it with water.
In the fall, the leaves of deciduous trees change color. This is because the chlorophyll, which is the green pigment that gives leaves their color, breaks down. The leaves then turn yellow, orange, and red. This process is called senescence.
