Why is dispersal of seeds necessary for growth of plants?
Dispersal of seeds help the plants to spread out and grow in new places, sometimes a long distance away from the parent plant. This is important because, if the seeds are not dispersed, a large number of germinating seedlings can grow very close to the parent plant. This will result in competition between all such seedlings, as well as the parent plant. The ‘competition is for getting light, space, water and nutrients; all of these are important for plants to be able to grow and survive. That is why dispersal of seeds necessary for growth of plants.
