Question

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

Dispersal of seeds is necessary so that seeds of a plant get scattered over a large area. If all the seeds of a plant fall at one place, they will not have enough space, water, minerals and the sunlight. Thus, they will not develop into healthy plants.
Following are the different agents of dispersal:
(a) Wind (e.g. cotton and maple seeds)
(b) Water (e.g. lotus seeds)
(c) Animals (Xanthium seeds)
(d) Explosion of fruit (e.g. geranium and balsam seeds)
