Seed, the characteristic reproductive body of both angiosperms (flowering plants) and gymnosperms (eg, 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.

Seed and fruit development the seed develops from the ovule and contains the embryo and endosperm, surrounded by the maternally derived seed coat the function of the seed is to protect the embryo, to sense environmental conditions favorable to germination and to nourish the germinating seedling.

The process of seed germination includes the following five changes or steps such five changes or steps occurring during seed germination are: (1) imbibition (2) respiration (3) effect of light on seed germination(4) mobilization of reserves during seed germination and role of growth regulators and (5) development of embryo axis into seedling. Seed development seed development comprises two major phases: embryo development and seed maturation embryogenesis, which is a morphogenesis phase, starts with the formation of a single-cell zygote and ends in the heart stage when all embryo structures have been formed (mayer et al, 1991.
