Pollen Grain Structure and Function
Pollen grains are the male gametophytes in seed plants, crucial for sexual reproduction. They consist of two main types of cells: the vegetative cell and the generative cell.
Generative Cell Role
- The generative cell is responsible for the formation of male gametes (sperm cells).
- Upon pollen grain germination, the generative cell undergoes mitotic division to produce two male gametes.
Process of Male Gamete Formation
- After pollination, the pollen grain lands on the stigma of a compatible flower.
- The vegetative cell develops into the pollen tube, while the generative cell divides.
- This division results in two haploid male gametes that travel down the pollen tube toward the ovule for fertilization.
Other Cells in Pollen Grain
- Vegetative Cell: It develops into the pollen tube but does not divide to form gametes.
- Microspore Mother Cell: This cell undergoes meiosis to produce microspores, which develop into pollen grains, but it is not involved in the direct formation of gametes.
Conclusion
The correct answer to the question is option 'B', the generative cell, as it specifically divides to create the two male gametes necessary for fertilization in plants. Understanding this process is essential for grasping plant reproductive biology, especially for competitive exams like NEET.

The development of the male gametophyte in angiosperms is called as microgametogenesis. Pollen grain is the first cell of a male gametophyte. This cell undergoes only two divisions, with the result of first division two cells are formed - a large vegetative cell and a small generative cell. The second division is concerned with generative cell only. This division may take place either in pollen grain or in the pollen tube and gives rise to two male gametes.
