The given figure shows a typical structure of monocotyledonous seeds. Identify the parts A, B, C, D and E marked in the given figures.
 

In the given figure of monocotyledonous seeds, the structure marked as A, B, C, D and E are respectively endosperm, embryo, scutellum, coleoptile and coleorhiza. Endosperm is the part of a seed which acts as a food store for the developing plant embryo, usually containing starch with protein and other nutrients.
Embryo is the part of a seed which develops into a plant, consisting (in the mature embryo of a higher plant) of a plumule, a radicle, and one or two cotyledons. Scutellum is the large shield like cotyledon of the embryo of certain monocots. It is specialized for the absorption of food from the endosperm. Coleoptile is the first leaf above the ground, forming a protective sheath around the stem tip. It surrounds the plumule. Coleorhiza is the sheath that envelops the radicle in certain plants and that is penetrated by the root in germination.
