Which of the following statements is correct ?

Options

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

Answer

To determine which statement is correct, let's analyze each option step by step.

### Step 1: Analyze the first statement
**Statement:** The seed in grass is not endospermic.
**Analysis:** This statement is incorrect. Grasses belong to the family Poaceae, and their seeds are indeed endospermic, meaning they contain endosperm. Endospermic seeds are also referred to as albuminous seeds.
**Conclusion:** This option is incorrect.

### Step 2: Analyze the second statement
**Statement:** Mango is a Parthenocarpic fruit.
**Analysis:** This statement is also incorrect. Parthenocarpic fruits develop without fertilization and typically do not contain seeds. However, mangoes have a large seed, indicating that they are true fruits formed after fertilization.
**Conclusion:** This option is incorrect.

### Step 3: Analyze the third statement
**Statement:** A proteinaceous eluron layer is present in the maize grain.
**Analysis:** This statement is correct. In monocot endospermic seeds, such as maize, the endosperm is surrounded by a single-cell thick layer known as the aleurone layer. The aleurone layer contains proteinaceous grains that are important during germination.
**Conclusion:** This option is correct.

### Step 4: Analyze the fourth statement
**Statement:** A sterile pistol is called a staminode.
**Analysis:** This statement is incorrect. A sterile stamen, not a sterile pistil, is referred to as a staminode. Therefore, the statement is misleading.
**Conclusion:** This option is incorrect.

### Final Conclusion
The only correct statement among the options provided is the third one: "A proteinaceous eluron layer is present in the maize grain."
