Mosses are commonly confused with liverworts, hornworts and lichens. [7] Although often described as non-vascular plants, many mosses have advanced vascular systems. [8] [9] Like liverworts and hornworts, the haploid gametophyte generation of mosses is the dominant phase of the life cycle.
The overall physical similarity of some mosses and leafy liverworts means that confirmation of the identification of some groups can be performed with certainty only with the aid of microscopy or an experienced bryologist. Liverworts, like other bryophytes, have a gametophyte-dominant life cycle, with the sporophyte dependent on the gametophyte ...

A protonema (plural: protonemata) is a thread-like chain of cells that forms the earliest stage of development of the gametophyte (the haploid phase) in the life cycle of mosses. When a moss first grows from a spore , it starts as a germ tube , which lengthens and branches into a filamentous complex known as a protonema , from which a leafy ...
The gametophyte is the first and dominant phase of two alternating phases in a bryophyte's life cycle. This part of the life cycle consists of protonema (the preliminary stage where the propagule develops green thread-like filaments), the rhizoids (filaments growing beneath the bryophyte that help anchor the bryophyte to its substratum), the stem, the leaves, its reproductive structure ...

Young sporophytes of the common moss Tortula muralis. In mosses, the gametophyte is the dominant generation, while the sporophytes consist of sporangium-bearing stalks growing from the tips of the gametophytes Sporophytes of moss during spring In flowering plants, the sporophyte comprises the whole multicellular body except the pollen and ...
Like all mosses, it utilizes alternation of generation. This means that during their life cycle, they alternate between two generations where they’re either in a sexual or asexual phase. In the gametophyte generation, this is where they produce gametes while in the sporophyte generation this is where they produce spores.
