DENDROLOGY

Detailed explanation-1: -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-2: -The outer covering of a seed is called the seed coat. Seed coats help protect the embryo from injury and also from drying out. Seed coats can be thin and soft as in beans or thick and hard as in locust or coconut seeds.

Detailed explanation-3: -Seed coat is the outermost covering of a seed. It helps in the protection of the seed from the physical stress such as shock, temperature variations or water damage.
