Question

Function of vegetative and generative cell.

• A. Vegetative cell forms pollen tube; generative cell forms two male gametes
• B. Both cells form pollen tubes
• C. Both cells form male gametes
• D. Generative cell forms pollen tube; vegetative cell forms male gametes

Hint:

The division of the generative cell into two male gametes is a crucial step in the fertilization process of flowering plants.

Answer 1

The Correct Option is A

In pollen grains, the vegetative cell forms the pollen tube, which grows down the style of the flower to deliver the male gametes to the ovule. The generative cell divides to form two male gametes (sperm cells), which fertilize the ovule. Thus, the correct answer is Vegetative cell forms pollen tube; generative cell forms two male gametes.
