MARKS App · Accepted Answer

The two cells of a pollen grain are vegetative cell and generative cell. The generative cell is a small spindle-shaped cell, which floats in the cytoplasm of the larger cell with an irregular nucleus. The larger cell is called the vegetative cell. It germinates on the stigma. It absorbs the sugary secretion and the cytoplasm comes out as a pollen tube. It does not divide.
