Question

what is the function of the pollen grain tube? Explain it with the help of a diagram​

Answer 1

Explanation:

Pollen tubes 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

Answer:

A pollen tube is part of the male gametophyte of seed plants. It acts as a conduit to transport the male gamete cells from the pollen grain, either from the stigma (in flowering plants) to the ovules. In maize, this single cell can grow longer than 12 inches to traverse the length of the pistil.
