If all seeds of a plant fall under the parent plant they will grow crowded together and many will die because of lack of space or air, water, sunlight and minerals. The scattering or spreading of seeds to different places is called seed dispersal. The seeds in the above example latched onto your pants to disperse, but they may also catch on the fur of animals. Seed - Seed - Dispersal by water: Many marine, beach, pond, and swamp plants have waterborne seeds, which are buoyant by being enclosed in corky fruits or air-containing fruits or both; examples of these plants include water plantain, yellow flag, sea kale, sea rocket, sea beet, and all species of Rhizophoraceae, a family of mangrove plants.

Other articles where Seed dispersal is discussed: “Flying” Trees: As in most tropical forests, the trees of Panama exhibit a variety of different adaptations to aid dispersal of their seeds. It might be outdated or ideologically biased. Learn more about seed characteristics, dispersal, and germination. These adaptations involve substantial investment of the trees’ material, but they are worthwhile because seed dispersal increases both the seeds’ and the species’ chances… Seed, the characteristic reproductive body of both angiosperms and gymnosperms.
