WebMoss Life Cycle. The mosses (and all bryophytes) have an alternation of generations life cycle that is unusual for two reasons: The haploid form is the dominant generation (larger, long-lived, and photosynthetic) The diploid form is the lesser generation (smaller, short lived and nutritionally dependent on the haploid form). WebAfter elongation of the moss sporophyte has ceased, the distal portion (farthest away) enlarges to form the capsule (sporangium), or spore-bearing region. The spores (meiospores), which arise by meiosis, are shed from the capsule gradually through a variety of mechanisms.After the operculum (cover) of the capsule has been shed, its mouth is …

WebIs the Moss a gametophyte or sporophyte? Mosses are heterosporous, which means they make two distinct types of spores; these develop into male and female gametophytes. That is, the sporophyte produces only one type of spore within a structure called the sporangium (Figure 20.3). One gametophyte can produce both male and female sex organs. Webmoss, (division Bryophyta), any of at least 12,000 species of small nonvascular spore-bearing land plants.
