The correct Answer is:
To determine which statement is correct, we will analyze each statement provided in the question step by step. 1. **Statement 1: Mango is a parthenocarpic fruit.** - Parthenocarpy refers to the development of fruit without fertilization. - Mangoes typically require fertilization for fruit development, thus this statement is **incorrect**. 2. **Statement 2: A proteinaceous alluron layer is present in our maize grain.** - The alluron layer is a protein-rich layer found in the seeds of certain plants, including maize (corn). - Since maize does have a proteinaceous alluron layer, this statement is **correct**. 3. **Statement 3: A sterile pistil is called staminode.** - A staminode is actually a sterile stamen, not a pistil. A sterile pistil is referred to as a pistillode. - Therefore, this statement is **incorrect**. 4. **Statement 4: The seeds in the grasses are not endospermic.** - Grasses belong to the Poaceae family, and seeds in this family are typically endospermic, meaning they contain endosperm for nourishment. - Hence, this statement is also **incorrect**. After evaluating all the statements, we conclude that the only correct statement is: **Correct Answer: Statement 2 - A proteinaceous alluron layer is present in our maize grain.**
