Aleurone layer helps in

Options

A. storage of food in endosperm
B. protection of embryo
C. utilization of stored food by secreting enzymes
D. All the above

Answer

### Step-by-Step Solution:

1. **Understanding the Aleurone Layer**:
- The Aleurone layer is a single cell thick layer found in monocot seeds, specifically in endospermic seeds. It surrounds the endosperm, which is the tissue that provides nourishment to the developing embryo.

2. **Function of the Aleurone Layer**:
- The primary function of the Aleurone layer is to utilize the stored food present in the endosperm. During the germination process, the Aleurone layer plays a crucial role in breaking down the stored nutrients.

3. **Mechanism of Action**:
- The Aleurone layer secretes enzymes that help in the conversion of the stored food in the endosperm into simpler forms that can be absorbed by the embryo. This process is essential for the growth of the embryo as it provides the necessary nutrients.

4. **Conclusion**:
- Therefore, the Aleurone layer helps in the utilization of stored food by secreting enzymes, which is vital for the growth of the embryo during germination.

### Final Answer:
The Aleurone layer helps in the utilization of stored food by secreting enzymes, which aids in the growth of the embryo.
