花粉管
1. (flower's) pollen tube
2. Pollen tubeThe pollen tubes is the male gametophyte of seed plants that 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. After pollination, the pollen tube germinates from the pollen grain and grows the entire length through the stigma, style, ovary and ovules to reach the egg cell.
