In botany, a seed is a plant structure containing an embryo and stored nutrients in a protective coat called a testa. More generally, the term seed means anything that can be sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote and grows within the mother plant to a certain size before growth is halted.
