The seed is thus a dormant embryo sporophyte with stored food and protective coats. When conditions are once more favorable, germination occurs and a new generation of plants develops. Fruits Fruits are a development of the ovary wall and sometimes other flower parts as well. As seeds mature, they release the hormone auxin , which stimulates the wall of the ovary to develop into the fruit. In fact, commercial fruit growers may stimulate fruit development in nonpollinated flowers by applying synthetic auxin to the flower.
Fruits promote the dispersal of their content of seeds in a variety of ways.
Nuts and berries entice animals to eat them. Some fruits, as they dry, open explosively expelling their seeds.
