Green bryophyte plants are gametophytes
Web- The sporophyte is diploid (2N), develops from the fusion of haploid male and female gametes and through meiosis produces haploid spores. The green, leafy generation of a given plant is called the dominant generation. For the bryophytes, the gametophyte is the dominant generation (Fig. 9.19 pg. 9-16 & Fig. 22.12 pg. 22-17). WebThe gametophyte (haploid) structures are shown in green, the sporophyte (diploid) in brown. Like all land plants (embryophytes), bryophytes have life cycles with alternation of generations. [11]

There have probably been several different terrestrialization events, in which originally aquatic organisms colonized the land, just within the lineage of the Viridiplantae. Between 510 - 630 million years ago, however, land plants emerged within the green algae.
