Question

The scutellum observed in a grain of wheat or maize is comparable to which part of the seed in other angiosperms?

• A. Cotyledon
• B. Endosperm
• C. Aleurone layer
• D. Plumule

Answer 1

The correct option is A

Cotyledon

Angiosperms are divided into monocots and dicots based on the number of cotyledons. In monocots, the seed consists of a single, large, shield-shaped cotyledon called scutellum. The scutellum is observed in a grain of wheat or maize is comparable to the cotyledons in other monocotyledons. In the seeds of cereals such as maize the seed coat is membranous and generally fused with the fruit wall. The endosperm is bulky and stores food. The outer covering of endosperm separates the embryo by a proteinous layer called aleurone layer.
