Detailed explanation-1: -endosperm, tissue that surrounds and nourishes the embryo in the seeds of angiosperms (flowering plants). In some seeds the endosperm is completely absorbed at maturity (e.g., pea and bean), and the fleshy food-storing cotyledons nourish the embryo as it germinates.

Detailed explanation-2: -Endosperm, unlike the cotyledon, originates by the union of male nuclei and polar nuclei of embryo sac. In dicots, endosperm is digested completely before the seed germinates, whereas cotyledon remains until the seedling is capable of photosynthesis. In dicots, cotyledon completely absorbs the food stored in endosperm.

Detailed explanation-3: -The suspensor absorbs and manufacturers nutrients from the endosperm that are utilized during the embryos growth.

Detailed explanation-4: -Either the nutrients surround the embryo in a tissue known as endosperm, as in a corn seed, or the nutrients are stored in leaf-like structures known as a cotyledons which are part of the embryo, as in bean seeds.

Detailed explanation-5: -Cotyledon is the embryonic leaf of the seed, which is capable of developing into the shoot of the plant during seedling. Endosperm contains required nutrients for the development of the embryo in the form of either starch, oil, or proteins.
