DENDROLOGY

Detailed explanation-1: -In a cereal grain (e.g. wheat), the single cotyledon of embryo is represented by the scutellum. Scutellum is specialised for nutrient absorption from the endosperm. Coleoptile is a modified ensheathing leaf that covers and protects the young primary leaves of a grass seedling.

Detailed explanation-2: -Scutellum is part of the structure of a barley and rice seed-the modified seed leaf. The scutellum can also refer to the equivalence of a thin cotyledon in monocots. It is very thin with high surface area, and serves to absorb nutrients from the endosperm during germination.

Detailed explanation-3: -The embryo in maize grain consists of a single cotyledon called a scutellum, a radicle, and a plumule.
