Each pollen grain produces ______ male gametes.
Open in App
Solution
The correct option is B Two
One thing to remember is that the pollen itself is not the male gamete. Each pollen grain contains vegetative or non-reproductive cells and a generative or reproductive cell. The vegetative cell is generally a single cell in most flowering plants but several in other seed plants. In flowering plants, the vegetative tube cell produces the pollen tube and the generative cell divides to form two sperm cells.
Thus, the correct answer is option (B), 'Two'.
