Seed Dispersal Done by Nice Nature
What is seed dispersal? Seed dispersal is the movement or transport of seeds away from the parent plant. There are three main modes of seed dispersal:wind,water and animalsseeds
What is wind dispersal? Wind dispersal is one of the more primitive means of dispersal. Wind dispersal can take on one of two primary forms: seeds can float on the breeze or alternatively, they can flutter to the ground.
Wind dispersal E.G:dandelion
What is water dispersal? The water lily is an example of such a plant. Water lilies' flowers make a fruit that floats in the water for a while and then drops down to the bottom to take growth on the floor of the pond.water lily plantflowersfruitwaterpond

What is animal dispersal? Seed predators, which include many rodents (such as squirrels) and some birds (such as jays) may also disperse seeds by hoarding the seeds in hidden caches. The seeds in caches are usually well- protected from other seed predators and if left uneaten will grow into new plants.
Animal dispersal E.G:bird
