Each microspore divide by mitotic division making a smaller generative cell and a larger vegetative cell or tube cell. If generative cell is damaged then the normal pollen tube will be formed because pollen tube is formed by vegetative cell, not by generative cell of microspore.

Explanation:
When a laser destroys the generative cell of a pollen grain, it can still grow a normal pollen tube because the vegetative cell is not damaged. The vegetative cell is responsible for growing the pollen tube and does not require the presence of the generative cell to do so. The generative cell is responsible for dividing to form sperm cells, which are needed for fertilization.
Therefore, even if the generative cell is destroyed, the vegetative cell can still grow a normal pollen tube towards the female reproductive structure. This is because the region of emergence of the pollen tube is not harmed by the laser beam. The contents of the killed generative cell do not stimulate pollen growth, nor does the laser beam stimulate the growth of the pollen tube.
In summary, the vegetative cell is not damaged by the laser, and is capable of growing a normal pollen tube without the presence of the generative cell.
