pollen tube
A pollen tube is a tubular structure produced by the male gametophyte of seed plants (pollen grain) after successful pollination. 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 at the base of the pistil or directly through ovule tissue in some gymnosperms. It plays a crucial role in the sexual reproduction of plants.
Wikidata
Pollen tube
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 to the ovules at the base of the pistil, or directly through ovule tissue in some gymnosperms. In maize, this single cell can grow longer than 12 inches to traverse the length of the pistil. Pollen tubes were first discovered by Giovanni Battista Amici.
