Question

Name some plants which are dispersed by-(a) wind (B) water(c) animals

Answer 1

Answer:

a. Seeds from plants like dandelions, swan plants and cottonwood trees are light and have feathery bristles and can be carried long distances by the wind. Some plants, like kauri and maple trees, have 'winged' seeds. They don't float away but flutter to the ground.

b.The water lily is an example of such a plant. Water lilies' flowers make a fruit that floats in the water for a while and then drops down to the bottom to take root on the floor of the pond. The seeds of palm trees can also be dispersed by water.

c.The seeds of some plants are dispersed by animals. Plants such as burdock have hooks to which the seed is attached. These hooks easily get caught in the fur of mammals as they pass by the plant. At some point the seed will fall, often a considerable distance from the parent.
