Q.Which one of the following statements is correct?

(a) A sterile pistil is called as a staminode.

(b) The seed in grasses is not endospermic.

(c) Mango is a parthenocarpic fruit.

(d) A proteinaceous aleurone layer is present in maize grain.

Solution :

Correct option : D The seed in grasses is endospermic. Grasses belong to Family Poaceae. These are monocots. They have albuminous seeds. Parthenocarpic fruit is a fruit which is developed without fertilization. They do not have seed. Mango is not a parthenocarpic fruit. A proteinaceous aleurone layer is present in maize grain. This layer surrounds the endosperm. A sterile pistil is called as a pistillode. A sterile stamen is called as staminode. Thus, the correct answer is option D.
