Seed Structure and Function

Bean Seed

Embryo- A young, developing plant, such as the rudimentary plant inside the seed of higher plants or that inside the archegonium of mosses and ferns

Endosperm-The nutritive tissue within seeds of flowering plants, surrounding and absorbed by the embryo.

Cotyledon-A leaf of the embryo of a seed plant, which upon germination either remains in the seed or emerges, enlarges, and becomes green.
 *The corn seed has only one cotyledon while the bean seed has two.
