Which one of the following statements is correct

Options

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

Answer

To determine which statement is correct among the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Evaluate the First Statement:**
- The first statement claims that a sterile pistil is called a staminose.
- **Analysis:** A sterile pistil is actually referred to as a "pistillate" or "pistilose," while a sterile stamen is called "staminose."
- **Conclusion:** This statement is incorrect.

2. **Evaluate the Second Statement:**
- The second statement claims that the seed in grasses is not endospermic.
- **Analysis:** Grasses, which belong to the family Poaceae, typically have seeds that are endospermic, meaning they contain endosperm that provides nourishment to the developing embryo.
- **Conclusion:** This statement is incorrect.

3. **Evaluate the Third Statement:**
- The third statement claims that mango is a parthenocarpic fruit.
- **Analysis:** Parthenocarpic fruits develop without fertilization and do not contain seeds. However, mangoes do develop seeds as a result of fertilization, so they are not classified as parthenocarpic.
- **Conclusion:** This statement is incorrect.

4. **Evaluate the Fourth Statement:**
- The fourth statement claims that a proteinaceous layer called the "LA eurone" layer is present in maize grain.
- **Analysis:** The "LA eurone" layer is indeed a protein-rich layer surrounding the endosperm in maize grains, providing nourishment. This statement accurately describes the structure and function of the layer.
- **Conclusion:** This statement is correct.

### Final Answer:
The correct statement is: **A proteinaceous LA eurone layer is present in maize grain.**
