Detailed explanation-1: -A seedling is a young plant or sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves).

Detailed explanation-2: -Most seeds consist of three parts: embryo, endosperm, and seed coat. The embryo is a tiny plant that has a root, a stem, and one or more leaves. The endosperm is the nutritive tissue of the seed, often a combination of starch, oil, and protein.

Detailed explanation-3: -Embryo: The baby plant which is present enclosed inside the seed coat is called the embryo. Three structures that form the embryo are radicle, plumule and cotyledons.

Detailed explanation-4: -Essentially, a seed consists of a miniature undeveloped plant (the embryo), which, alone or in the company of stored food for its early development after germination, is surrounded by a protective coat (the testa).

Detailed explanation-5: -The embryo is a miniature plant in a state of arrested development. The embryo’s food, called endosperm, may be in the seed leaves (also called cotyledons) or it may be outside the seed leaves and be absorbed as the seed germinates.
