The pollen tube grows through the stigma and style to the ovary. In a two-celled pollen (vegetative and generative), the generative cell divides to form two male gametes during pollen tube growth.

| Text | Pollen tube grows through the tissues of the stigma and style and reaches the ovary. In some plants, pollen grains are shed at two-celled condition (a vegetative cell and a generative cell). In such plants, the generative cell divides and forms the two male gametes during the growth of pollen tube in the stigma. |
