WebThe sexual phase, called the gametophyte generation, produces gametes, or sex cells, and the asexual phase, or sporophyte generation, produces spores asexually. In terms of … WebThe male gametophyte is briefly separated from the sporophyte when pollen is released into the wind. These pollen grains contain an immature male gametophyte enclosed and dispersed in the microspore wall (Figure 5). In the Pinaceae, three successive divisions of the microspore produce a four-celled pollen grain within the microsporangium.
