What are the three main parts of a seed and what do they do?
The main parts of a bean are inside the seed coat, these are the endosperm, cotyledon, and the hypocotyl. The endosperm surrounds the embryo and provides nutrition in the form of starch. The cotyledon is the significant part of the embryo within the seed of the been. It becomes the first leaves of a seedling upon germination. The hypocotyl is the stem of the germinating seedling found below the cotyledon.
