Which one of the following statements is correct

Options

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

Answer

To solve the question "Which one of the following statements is correct?", we will analyze each given statement step by step.

### Step 1: Analyze the first statement
**Statement:** "The seed in grasses is not endospermic."

- Grasses belong to the family Poaceae, and their seeds are indeed endospermic. This means they contain endosperm, which is a tissue produced inside the seeds of most flowering plants, providing nutrition to the developing embryo.
- **Conclusion:** This statement is incorrect.

### Step 2: Analyze the second statement
**Statement:** "Mango is a parthenocarpic fruit."

- Parthenocarpic fruits develop without fertilization and are typically seedless. However, mangoes do contain seeds, which means they are not parthenocarpic.
- **Conclusion:** This statement is also incorrect.

### Step 3: Analyze the third statement
**Statement:** "A proteinaceous alluronic layer is present in the maize grain."

- The maize grain (corn) does indeed contain a proteinaceous layer known as the alluronic layer, which is rich in proteins and serves as a source of nutrition for the developing seed.
- **Conclusion:** This statement is correct.

### Step 4: Analyze the fourth statement
**Statement:** "A sterile pistil is called a staminoid."

- A sterile pistil is not called a staminoid; rather, it is referred to as a pistilloid or pistilate. The term "staminoid" refers to a sterile stamen.
- **Conclusion:** This statement is incorrect.

### Final Conclusion
After analyzing all the statements, we find that the only correct statement is the third one: "A proteinaceous alluronic layer is present in the maize grain."

### Answer:
The correct answer is option C.
