Question

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

1. A. Coleoptile
2. B. Coleorhiza
3. C. Integument
4. D. Aleurone layer (Correct answer)

Correct Answer

Option D — Aleurone layer

Detailed Solution & Explanation

The correct answer is Aleurone layer.

Key Points

• In monocot (cereal) seeds, the outer covering of the endosperm is a proteinaceous layer called the aleurone layer, which separates the embryo from the endosperm.
• Coleoptile and coleorhiza are protective sheaths of the plumule and radicle; integument becomes the seed coat.
