Plant Diversity The scales of the female cones bear ovules, which enclose the female sporangia. Cells in the female sporangia also undergo meiosis to produce spores. One of the spores from each meiotic division develops into a female gametophyte by mitosis. As the pollen germinates and produces sperm nuclei by mitosis, the female gametophyte produces an egg. One sperm nucleus reaches the egg through the pollen tube and fertilizes it. Notice in Figure 6 that the male gametangium has been...
