Pollen tubes

Definition (http://en.wikipedia.org/wiki/Pollen_tubes)

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 at the base of the pistil, or directly through ovule tissue in some gymnosperms. (Wikipedia)
