Seeds
In botany, the seed is a means of plant reproduction and propagation, in addition to being a storehouse of energy and food.
A seed is a fertilized egg formed from the ovary of a flower, and it is the basis for reproduction in higher plants and from which the life of a new generation begins.
A seed can be defined as a small embryonic plant in a state of dormancy, and the seed consists of the embryo surrounded by a sheath called the basra, and a quantity of stored food either stored in some parts of the embryo, or separated from it in a special tissue called the endosperm. The seed in the first case is not endosperm, and in the second case it is endosperm. In the endosperm seed, nutrients are often stored in the cotyledons, which appear full, large and greasy.
As for the embryo, it is composed of the same basic organs that make up the adult plant, which are the root, stem and leaves, but in a very miniature form, the embryonic root is called the rhizome, and the embryonic stem is called the feather. The number of cotyledons in angiosperms varies, so the seed in monocotyledons consists of one seed (hence the name), for example the seeds of wheat, corn, barley and palm, and the seed consists of two cotyledons in dicotyledons such as beans, lentils, beans, castor, cotton and most tree species.
