Solution
The correct option is A vegetative cell is not damaged
The generative cell of a pollen was destroyed by laser but a normal pollen tube was still formed because the vegetative cell of the pollen was not damaged.
In a pollen grain, there are usually two cells - the generative cell and the vegetative cell.
Generative cell further divides to give rise to two male gametes while the vegetative cell gives rise to the pollen tube. So, while the destruction of the generative cell will ensure that no male gametes are formed, the vegetative cell will give rise to the pollen tube as long as it is unharmed.
