The proteinaceous endosperm of maize is called

Options

A. Apophysis
B. Scutellum
C. Aleurone layer
D. None of the above

Answer

To solve the question about the proteinaceous endosperm of maize, let's break down the information step by step:

### Step-by-Step Solution:

1. **Understanding Endosperm**:
- The endosperm is a tissue produced during the double fertilization process in angiosperms. It serves as a food reserve for the developing embryo.

2. **Types of Endosperm**:
- In maize (a monocot), the endosperm is typically starchy and contains protein. It is important to identify the specific layers or parts of the endosperm.

3. **Identifying the Layers**:
- The endosperm of maize consists of different layers. One of these layers is known as the **alurone layer**, which is rich in proteins.

4. **Other Options**:
- **Apophysis**: This term does not refer to any part of the maize endosperm.
- **Scutellum**: This is the large shield-shaped cotyledon found in monocots, but it is not the proteinaceous layer.
- **None of the above**: This option can be eliminated since we have identified the correct term.

5. **Conclusion**:
- The proteinaceous endosperm of maize is specifically referred to as the **alurone layer**.

### Final Answer:
The proteinaceous endosperm of maize is called the **alurone layer**.
