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 proteinaceous aleurone layer is present in maize grain.
D. A sterile pistil is called a stamionde.

Answer

To determine which statement is correct, we will evaluate each of the provided options one by one.

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

**Analysis:**
- Grasses are classified as monocotyledons, and in monocots, the seeds typically contain endosperm, which serves as a food reserve for the developing embryo.
- Therefore, this statement is **incorrect**.

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

**Analysis:**
- Parthenocarpy refers to the development of fruit without fertilization, resulting in seedless fruits.
- Mangoes do contain seeds, which means they are not parthenocarpic.
- Therefore, this statement is also **incorrect**.

### Step 3: Evaluate the third statement
**Statement:** A proteinaceous allurane layer is present in the maize grain.

**Analysis:**
- Maize (corn) grains do have a proteinaceous layer called the aleurone layer, which is rich in proteins and enzymes that help in the germination process.
- Therefore, this statement is **correct**.

### Step 4: Evaluate the fourth statement
**Statement:** Sterile pistil is called Stemion Day.

**Analysis:**
- The term "Sterile Pistil" does not refer to "Stemion Day." The correct term for a sterile pistil is "Pistillate."
- Therefore, this statement is **incorrect**.

### Conclusion
After evaluating all the statements, the only correct statement is the third one: "A proteinaceous allurane layer is present in the maize grain."

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