Cotyledon is a significant part of plant embryo within the seed. It stores food materials that are supplied to the seeds at the time of germination. After germination the cotyledons become the first leaf of the seedling. When the seedling grows into a small plant with new leaves, the cotyledon dries up and shed down. Cotyledon functions in initial days of a plant life. The number of leaves or flowers grown in the plants do not depend upon cotyledon.
