The very top row are the microspores that will give rise to microgametophytes, I'll try to call them male spores and male gametophytes and in the middle we have megaspores that give rise to megagametophytes and I'll try to call them female gametophytes. After fertilization, the diploid sporophyte grows out of the archegonium on the gametophyte, and the sporophyte eventually grows much larger than the gametophyte and becomes the free-living, dominant form of the life cycle. In fact, Selaginella apoda has the shortest life cycle of all Selaginella species. The Life Cycle of Selaginella. Some species reproduce by vegetative reproduction 19. Reproduction of selaginella.
