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 "The proteinaceous endosperm of maize is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Maize Seed**:
- Maize (Zea mays) is classified as a monocotyledonous plant. This means that its seeds have one cotyledon and contain an endosperm, which is a tissue that provides nutrition to the developing embryo.

2. **Identify the Type of Endosperm**:
- The endosperm in maize seeds is primarily composed of starch and proteins. It serves as a food reserve for the seed.

3. **Focus on the Proteinaceous Component**:
- Within the endosperm, there is a specific layer that is rich in proteins. This layer is crucial for the nutrition of the developing seedling.

4. **Name the Proteinaceous Layer**:
- The outer layer of the endosperm in maize is known as the **aleurone layer**. This layer is one cell thick and is packed with proteinaceous substances.

5. **Conclusion**:
- Therefore, the proteinaceous endosperm of maize is specifically referred to as the **aleurone layer**.

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