Document Summary
Endosperm : surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils andprotein. Cotyledons : embryo within the seed of a plant. May become the embryonic first leaves of a seedling. Endospermic: embryo is small relative to the rest of the seed. This is used up at the time of germination.
