Question

Which one of the following statements is correct?

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

Answer 1

The Correct Option is B

To determine the correct statement, let's evaluate each option:

1. Mango is a parthenocarpic fruit:
   Parthenocarpy is a phenomenon where fruits develop without fertilization. Mangoes develop from fertilized ovules, making this statement incorrect.
2. A proteinaceous aleurone layer is present in maize grain:
   The aleurone layer is indeed present in maize grains. It is rich in proteins and plays a vital role in seed metabolism, making this statement correct.
3. A sterile pistil is called a staminode:
   A staminode is a sterile stamen, not a pistil. A sterile pistil is usually called a pistillode, making this statement incorrect.
4. The seed in grasses is not endospermic:
   Most grass seeds, including those of cereals like rice and wheat, are endospermic. They have a large amount of endosperm that provides nutrition to the developing plant, making this statement incorrect.

Upon evaluating all the options, the correct statement is that a proteinaceous aleurone layer is present in maize grain.
