Aleurone layer occurs in the peripheral region of

Options

A. Endosperm
B. Coleoptile
C. Cotyledon
D. Coleorhiza

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks where the aleurone layer is located. The options provided are endosperm, colipatile, cotyledon, and coliureza.

2. **Analyzing the Options**:
- **Endosperm**: The endosperm is a tissue that provides nourishment to the developing embryo in seeds. It is primarily composed of starch and proteins.
- **Colipatile**: This is a protective sheath that surrounds the plumule (the shoot part of the embryo). It does not contain the aleurone layer.
- **Cotyledon**: This is the first leaf or leaves that develop from the embryo of a seed. It serves as a food source for the developing plant but does not have the aleurone layer.
- **Coliureza**: This term seems to be a misspelling or confusion with other terms related to plant morphology. It does not refer to a structure containing the aleurone layer.

3. **Identifying the Correct Answer**: The aleurone layer is specifically found in the peripheral region of the endosperm. It is a one-cell thick layer that surrounds the starchy endosperm and plays a role in seed germination and nutrient mobilization.

4. **Conclusion**: Based on the analysis, the correct answer to the question is **endosperm**.

### Final Answer:
The aleurone layer occurs in the peripheral region of **endosperm**.
