Animals also help spread seeds by consuming fruit that has seeds. When animals excrete their waste, seeds end up in other locations. Life Science: Session 4 - Learner The “wings” of maple seeds or the “parachutes” of dandelions carry them in the wind away from the parent plant. People and pets may even have carried seeds away from plants that bear fruit as burrs. Fleshy fruits tend to be adapted for dispersal by animals, who are attracted to them as food. Seed dispersal - Wikipedia Seed dispersal is the movement, spread or transport of seeds away from the parent plant. Plants have very limited mobility and consequently rely upon a variety of dispersal vectors to transport their propagules, including both abiotic vectors such as the wind and living vectors like birds.Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in ...
