Which of the following carries the male gametes to the ovule containing the female gamete?
pollen tube
During fertilisation, the pollen grains germinate on the stigma and the pollen tube develops. The pollen tube moves downward into the style. These tubes are the carriers of the male gametes. One pollen tube enters the ovule where the female gametes are present. The male gamete fuses with the female gamete completing the process of fertilisation.
