Mosses are widely distributed from the Arctic through the tropics to parts of Antarctica. The gametophytic plant body is with leafy axis and shows a radial symmetry. The rhizoid are multicellular, branched and have oblique septa. Sex organs, i.e., antheridia and archegonia are usually borne in groups at the apices of reproductive branches. The sporophyte is usually differentiated into foot, seta and capsule.
