Seed dispersal is important in plant reproduction because it helps plants colonize new areas, thus increasing their chances of survival and genetic diversity. By dispersing seeds away from the parent plant, plants reduce competition for resources and increase the likelihood of successful germination and growth. Seed dispersal also helps plants adapt to changing environments and avoid inbreeding, which can lead to healthier and more resilient populations. Overall, seed dispersal plays a crucial role in the reproductive success and long-term survival of plants.
