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

Within pollen grains, the vegetative cell is responsible for developing the pollen tube. This tube extends down the flower's style to transport the male gametes to the ovule. Concurrently, the generative cell undergoes division to produce two male gametes (sperm cells) that will subsequently fertilize the ovule.Therefore, the accurate statement is: The vegetative cell forms the pollen tube, and the generative cell forms two male gametes.
