Question

YESPYQ · Accepted Answer

Correct answer: d) A proteinaceous aleurone layer is present in maize grain. A. A sterile pistil is called a staminode: This statement is incorrect. A sterile pistil (the female reproductive organ) is called a pistillode, while a sterile stamen (the male reproductive organ) is called a staminode. B. The seed in grasses is not endospermic: This statement is incorrect. Seeds in grasses (which are monocots) are typically endospermic (albuminous), meaning they retain the endosperm tissue for nourishment. C. Mango is a parthenocarpic fruit: This statement is incorrect. Parthenocarpic fruits develop without fertilization and are typically seedless (e.g., banana, grapes). Mangoes develop from a fertilized ovary and contain a seed. D. A proteinaceous aleurone layer is present in maize grain: This statement is correct. The maize grain (a type of fruit where the fruit wall is fused with the seed coat) has a distinct outer layer of the endosperm called the aleurone layer, which is rich in proteins and separates the embryo from the starchy endosperm.
