Biology · HSEXUAL REPRODUCTION IN FLOWERING PLANTS

In flowering plants where pollen grains are shed at the 2-celled stage, when and where do the two male gametes form?

1. The vegetative cell divides mitotically inside the ovary
2. The generative cell divides mitotically during pollen tube growth in the stigma/style
3. The generative cell undergoes meiosis inside the synergid
4. The vegetative cell divides meiotically prior to reaching the micropyle
