takes  place giving  rise to a protonema, which develops into a new gametophyte plant. The gametophyte  generation or haploid phase of the moss is from the production  of haploid spores after meiosis  to the period just before fusion of the haploid antherizoid or haploid ovum. The sporophyte generation or diploid  phase is from the diploid  mother cells just before meiosis.
