seed

The fertilized and ripened ovule of a seed plant, comprising a miniature plant usually accompanied by a supply of food (endosperm) enclosed in a protective seed coat, often accompanied by auxiliary structures, and capable, under suitable conditions, of independent development into a plant similar to the one that produced it. In rice, the grain is the common form of seed; the caryopsis is the true seed.
