Detailed explanation-1: -The seed contains the embryo of a plant. Seeds have a hard outer cover that protects the embryo inside. Cotyledons in the seed store food for the growing embryo.
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.
Detailed explanation-3: -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. The zygote is the new sporophyte generation.
Detailed explanation-4: -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.
