parts of the seed

Their primary role is to protect the seed itself, so it can survive until spring and produce a new plant. 1993. (Click here to read relevant update). It is the embryo that ultimately gives rise to a new plant. It results from the union of a sperm (1N), from a germinated pollen, with a female egg (1N) in the embryo sac. The cotyledons provide nourishment to different parts of the embryo. All seeds are different and require different conditions to germinate and grow properly. In this case the cotyledons, not the endosperm, serve as the food-storage tissue. A thick seed coat protects the seed from sunlight and water. With monocot seeds, the embryo develops into a full-grown plant, and the endosperm is there to act as a source of food. Gravity. Seeds: Time Capsules of Life. VERHEIJ EWM, CORONEL RE, eds. Scientifically, it is the name for the fleshy or dry ripened ovary of a flowering plant enclosing a seed or seeds.
