Seed, the characteristic reproductive body of both angiosperms (flowering plants) and gymnosperms (e.g., conifers, cycads, and ginkgos).Essentially, a seed consists of a miniature undeveloped plant (the embryo), which, alone or in the company of stored food for its early development after germination, is surrounded by a protective coat (the testa).). Communication pathways between the endosperm and the seed coat are now beginning to be unravelled. ABA regulates many genes under osmotic stress conditions.
