Explain the structure of seeds in flowering pla... - SS3 Biology Development Of New Seeds Question

Seeds are the mature ovules of flowering plants. They consist of three main parts: the seed coat, endosperm, and embryo. The seed coat, derived from the integuments of the ovule, provides protection to the inner parts of the seed. The endosperm is a nutritive tissue that stores reserve food materials, such as starch and proteins, to support the initial growth of the germinating seedling. The embryo contains the embryonic root (radicle), embryonic shoot (plumule), and one or two cotyledons, which eventually develop into the first leaves of the seedling.
