In the seeds of cereals, the outer covering of endosperm separates the embryo by a protein-rich layer called:
The proteinaceous layer separating the embryo from the endosperm in cereals is the aleurone layer.
In monocot cereal seeds (such as maize), the outer covering of the endosperm separates the embryo by a special proteinaceous layer termed the aleurone layer.

The scutellum observed in a grain of wheat or maize is comparable to which part of the seed in other monocotyledons?In the grains of the grass family (wheat, maize, rice) the embryo is small and lies in a groove at one end of the endosperm.
It consists of one large, shield-shaped cotyledon known as the scutellum, and a short axis with a plumule and a radicle.
So the scutellum is the single cotyledon of the monocot embryo.
The aleurone layer is the protein-rich outer layer of the endosperm, and the plumule is the shoot tip enclosed in the coleoptile.
Hence the scutellum is comparable to the cotyledon.
