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

Explanation

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

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- **Statement:** "Proteinaceous allurean layer is present in maize grain."
- **Explanation:** The proteinaceous allueran layer is indeed found in maize grains. This layer surrounds the endosperm and is rich in proteins, making this statement correct.

2. **Analyze the Second Statement:**
- **Statement:** "A sterile pistil is called as taminoid."
- **Explanation:** This statement is incorrect. A sterile pistil is not referred to as a "taminoid." Instead, a sterile stamen is called a "staminode." Therefore, this statement is false.

3. **Analyze the Third Statement:**
- **Statement:** "Seed in grasses is not endospermic."
- **Explanation:** This statement is also incorrect. Seeds in grasses are indeed endospermic, meaning they contain endosperm which provides nourishment to the developing embryo. Thus, this statement is false.

4. **Analyze the Fourth Statement:**
- **Statement:** "Mango is a parthenocarpic fruit."
- **Explanation:** This statement is incorrect as well. Mangoes require fertilization to develop into fruit, which means they are not parthenocarpic. Parthenocarpic fruits develop without fertilization. Therefore, this statement is false.

5. **Conclusion:**
- After analyzing all the statements, the only correct statement is the first one: "Proteinaceous allurean layer is present in maize grain."

### Final Answer:
The correct statement is: **"Proteinaceous allurean layer is present in maize grain."**
