Question

In the seeds of cereals, the outer covering of endosperm separates the embryo by a protein-rich layer called ______.

Options

• Coleoptile

• Coleorhiza

• Integument

• Aleurone layer

Answer 1

In the seeds of cereals, the outer covering of endosperm separates the embryo by a protein-rich layer called aleurone layer.

Explanation:

In cereal grains like wheat and maize, the aleurone layer is high in protein. It is located between the endosperm and the embryo and is essential for germination because it secretes enzymes, such as amylase, that break down stored starch. On the other hand, the roots and shoots are shielded by the coleoptile and coleorhiza, respectively.
