Step-by-step solution

In monocotyledonous seeds (like maize), the embryo is small and situated in a groove at one end of the endosperm. It consists of a single large and shield-shaped cotyledon known as the scutellum. The aleurone layer is the proteinous outer covering of the endosperm. The coleoptile is the sheath enclosing the plumule, and the epiblast is a rudimentary second cotyledon present in some grasses. Answer: Scutellum
