The microstrobilus is made up of many microsporophylls in a cluster around a central stem. The female plant has an ovulate spur shoot, containing dichotomously veineted leaves and ovules. The ovule is the region which is to be pollinated. At this point the megaspore tetrad develops into a free nuclear megagametophyte. The pollen tube connects the male gametophyte to the megasporangial tissue.
Further development leads to the formation of the seed.
This contains the old sporophyte, the embryo, and the megagametophyte. Each seed of life begins a whole new plant of either male or female nature for the propogation of the Ginkgo kind.
