Which one of the following statements is correct?

Options

A. A proteinaceous aleurone layer is present in maize grain.
B. A sterile pistil is called a staminode
C. The seed in grasses is not endospermic.
D. Mango is a parthenocarpic fruit.

Answer

To determine which statement is correct, let's analyze each of the provided statements step by step.

### Step-by-Step Solution:

1. **Statement 1: There is a proteinaceous alleron layer present in the maize grain.**
- **Analysis:** The maize grain contains an endosperm, which is surrounded by an aleurone layer. The aleurone layer is indeed made up of proteinaceous cells. Therefore, this statement is **correct**.

2. **Statement 2: A sterile pistil is called the staminode.**
- **Analysis:** A staminode refers to a sterile stamen, not a pistil. Therefore, this statement is **incorrect**.

3. **Statement 3: The seed in the grasses is not androspermic.**
- **Analysis:** Grasses belong to the Poaceae family, which typically have albuminous seeds, meaning they contain endosperm. Thus, this statement is **incorrect**.

4. **Statement 4: The mango is a parthenocarpic fruit.**
- **Analysis:** Parthenocarpic fruits develop without fertilization and do not contain seeds. However, mangoes do have seeds, which means this statement is also **incorrect**.

### Conclusion:
The only correct statement is **Statement 1: There is a proteinaceous alleron layer present in the maize grain.**
