A typical seed consists of the following parts: (i) Seed coat - It is the outer covering of the seed and develops from the integument of the ovule. Angiosperm seeds are produced in a hard or fleshy structure called a fruit that encloses the seeds for protection in order to secure healthy growth. This means that plants have evolved many solutions to propagating themselves successfully. The scutellum is generally shield-shaped and is located laterally towards a side of the embryo axis. Internal structure — The seed is covered by a hard, tough covering called testa. Seeds are produced in several related groups of plants, and their manner of production distinguishes the angiosperms ("enclosed seeds") from the gymnosperms ("naked seeds"). Students construct an explanatory model describing the parts of a seed, namely the embryo, cotyledon, and seed coat. The endosperm nucleus also divides by mitosis and forms the endosperm tissue, which provides food for the developing embryo.
