Question

A pollen tube, produced from the pollen grain, contains ........... male gametes.

• A. One
• B. Two
• C. Seven
• D. Eight

Answer 1

Answer: (B)

Two

• The pollen grain is produced and released from the anthers of the stamens in the flower.
• The pollen grain lands on the stigma and the pollen tube is produced. There are two cells inside the pollen grain, vegetative cell and generative cell.
• The generative cell divides mitotically to form two male gametes which move with the pollen tube towards the micropylar end.
• Thus, the correct answer is option B.
