Corn is a monocotyledonous plant. The seed of corn is composed of seed coat, embryo and endosperm. Nutrients are stored in the endosperm. The cotyledons have the function of transporting nutrients. The difference between monocotyledons and Gemini is whether two cotyledons or one cotyledons are developed in the embryo of seeds. Two are called dicotyledons and one is called monocotyledons.
