Question

Write the function of pollen tube ?​

Answer 1

Pollen tubes are produced by the male gametophytes of seed plants. They act as conduits to transport the male gamete cells from the pollen grain—either from the stigma (in flowering plants) to the ovules at the base of the pistil or directly through ovule tissue in some gymnosperms.

Answer 2

The pollen tube is the tube through which sperm from the pollen reaches the egg cell, and fertilises the plant to form seeds. The pollen tube of most seed plants acts as a passageway. It transports sperm cells from the pollen grain, from the stigma (in flowering plants) to the ovules at the base of the pistil.
