Step 1
Angiosperm seeds include endosperm, a substance that protects and feeds the developing embryo (flowering plants). In some seeds (like pea and bean seeds), the endosperm is totally absorbed at maturity, and the fleshy, food-storing cotyledons feed the developing embryo.
By providing nutrition, shielding the embryo, and regulating embryo growth by functioning as a mechanical barrier throughout seed development and germination, the endosperm supports embryonic growth in a significant way.
