WebMay 4, 2024 · Bryophyte Lineages This evolutionary group includes liverworts (phylum Marchantiophyta, Figure 6.2. 4 ), mosses (phylum Bryophyta, Figure 6.2. 5 ), and hornworts (phylum Anthocerophyta, Figure 6.2. 6 ). There are approximately 23,000 known extant species, most of these belonging to the mosses. WebOne morphological character shared by all three bryophyte groups is the dominance of the gametophyte generation. The bryophyte gametophyte is typically perennial, free-living, and photosynthetic; while the sporophyte is short-lived and completes its entire life attached to the maternal gametophyte (Goffinet & Shaw 2009).

WebBryophytes are divided into three divisions: I. Ilepatieopsida (Liverworts): Liverworts are the simplest bryophytes. They grow on moist rocks and wet soil. Their plant body is gametophyte. There are two forms of gametophytes. Some have thallus body. Thallus is flat or ribbon-like. It is attached to soil by means of rhizoids. Example: Marchantia.
