Question

5. Why is dispersal of seeds necessary? Name the agents of dispersal giving one example each of
a seed that is dispersed by them ​

Answer 1

Answer:

Dispersal by Wind – Seeds of cotton or dandelion have tiny hair surrounding them, while the maple seed has wings attached to it. Dispersal by Water – The coconut seed has a thick coat of fibre that enables it to float in water.

Explanation:

If seeds are not dispersed, many germinating seedlings will grow very close to the parent plan. This results in competition between every one of the seedlings as well as with the parent plant. The competition is for light, water, space and nutrients.
