Pollen contains the male gamete for plants.

What kind of cells are pollen cells?

Answer: Each pollen grain contains vegetative (non-reproductive) cells (only a single cell in most flowering plants but several in other seed plants) and a generative (reproductive) cell. In flowering plants the vegetative tube cell produces the pollen tube, and the generative cell divides to form the two sperm cells.

A Pollen Cell is called a Generative Cell
