植物果实和种子的传播方式
英文回答:
Seed dispersal: The process by which seeds are moved away from the parent plant, either actively or passively.
Types of seed dispersal:
Ballistic dispersal: Seeds are ejected from the fruit with great force, such as in wood sorrel and common broom.
Wind dispersal: Seeds are light and have structures that help them catch the wind, such as wings or parachutes, as in dandelion and maple.
Water dispersal: Seeds are dispersed by water, either by floating on the surface or being carried by currents, as in water lilies and coconuts.
Animal dispersal: Seeds are dispersed by animals,
either by being eaten and passed through the digestive system or by being attached to the animal's fur or feathers, as in apples and burrs.
Gravity dispersal: Seeds fall from the fruit due to gravity, as in acorns and daisies.
Fruit dispersal: The process by which fruits are moved away from the parent plant, either actively or passively.
Types of fruit dispersal:
Wind dispersal: Fruits have structures that help them catch the wind, such as wings or parachutes, as in

中文回答:
种子传播,种子通过主动或被动的方式从母株移出的过程。

种子传播方式:
弹射传播,种子以极大的力从果实中弹出,如酢浆草和金雀花。

风传播,种子很轻,有帮助它们抓住风的结构,如蒲公英和枫
树中的翅膀或降落伞。

水传播,种子通过水传播,要么漂浮在水面,要么被水流带走,如睡莲和椰子。

动物传播,种子由动物传播,要么被吃掉并通过消化系统排出,要么附着在动物的皮毛或羽毛上,如苹果和毛刺。

重力传播,种子由于重力从果实中掉落,如橡子和小雏菊。

果实传播,果实通过主动或被动的方式从母株移出的过程。
