Most organisms don’t spend their whole lives in the place they were born. Dispersal: . movement of organisms away from a given population or parent.

A fruit develops from the ovary of a flower after pollination and ovule development have occurred. Fruit functions, not only to surround and protect the developing seeds, but more importantly, to accomplish dispersal. There are many strategies of seed dispersal, including . Seed Coat. Leaf. Root.
