Expert Answer:

A seed is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants. Seeds are developed from ovules. In angiosperms, seed is the final product of sexual reproduction. Seeds have better adaptive strategies for dispersal to new habitats and help the species to colonise in other areas. As they have sufficient food reserves, young seedlings are nourished until they are capable of photosynthesis on their own. The hard seed coat provides protection to the young embryo. Seeds generate new genetic combinations leading to variations. Seed is the basis of our agriculture.
