DENDROLOGY

Detailed explanation-1: -The development of the seed plant is basically different from that of an animal. The egg cell of a seed plant is retained within the enlarged lower part, or ovary, of the seed-bearing organ (pistil) of a flower.

Detailed explanation-2: -The seed is the embryonic stage of the plant life cycle. 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: -The outer covering of a seed is called the seed coat. Seed coats help protect the embryo from injury and also from drying out.

Detailed explanation-4: -Thus, a seed is an embryo and stored food enclosed in a seed coat. The development of a seed, also known as the ripening of an ovule, involves three distinct developmental processes: The development of a zygote into an embryo.
