the aleurone layer in maize grain is specially rich in which of the following molecules

1. starch
2. protein
3. lipids
4. cellulose

Hello student
correct answer is 2. Proteins
In monocotyledons the seeds are generally endospermous. the endosperm is surrounded by a special one cell thick layer called aleurone layer. It is filled with aleurone grains which are proteinaceous in nature other components of this layer are phytin, carbohydrates and small amounts of phospholipids are also present.

The correct answer is (2) Protein. The aleurone layer is rich in protein.

Aleurone is a protein found in protein granules of maturing seeds and tubers. The aleurone layer is the outermost layer of the endosperm, followed by the inner starchy endosperm.
