Seed dispersal is the transportation of the seeds away from the parent plant. Seed dispersal helps the plant species continue to grow and spread. There are three main ways of seed dispersal: animal, wind, water. The shape of the seeds that are dispersed by wind are usually winged shaped or shaped like parachutes like the picture above. Seeds dispersed by animals are sharp and haves spines making it easier to attach to the skin or fur of an animal. While lastly seeds dispersed by water are buoyant and can spend months out at sea without dying.
