Mosses are small flowerless plants. They usually grow in dense green clumps or mats. All mosses have rhizoids, which are anchoring structures, that look root-like, but don't have the absorptive functions of true roots.
The individual plants are usually composed of simple leaves that are generally only one cell thick, and are attached to a stem.
Mosses don't have seeds, but instead grow sporophytes (a spore-containing capsule, possibly sitting atop a stalk) with single capsules containing spores.
More information can be found on wikipedia or the Australian National Herbarium.
Mosses reproduce by branching and fragmentation, by regeneration from tiny pieces of photosynthetic tissues, and by the production of spores.
Spores (reference https://www.britannica.com/plant/moss-plant)
Mosses have an alteration of generations (metagenesis), between (a) the independent gametophyte generation, which produces the sex organs and sperm and eggs, and (b) the dependent sporophyte generation, which produces spores.
Mosses differ from one another primarily in the structure and specialisation of their spore cases (sporangia).
The stemlike and leaflike structures of moss plants constitute the sexual (gametophytic) generation - the gametophyte.
The asexual (sporophytic) generation develops from the gametophyte and usually consists of a raised stalk (called a seta), which terminates in the sporangium (a capsule containing spores, which are released).
The sporangium remains dependent on the gametophyte, to varying degrees, for water and nutrients.
The spore, under favourable conditions, germinates and grows into a branching green thread, the protonema. The gametophyte then grows from a small bud produced by a cell of the protonema that divides and differentiates.
