Gemmae propagules Fragmentation Gametophyte generation is the predominant and assimilative stage. Mosses attach to their substrate with multi cellular rhizoid. Mosses are found in a range of habitats, although moist and shady habitats are more common. Some mosses are found on rocks and in arid locations. As mentioned, mosses form huge masses in bogs throughout the world.
Mosses are often epiphytes.
Most water absorption is from the surface cells of the moss plant. Like most Bryophytes, mosses can desiccate, or dehydrate for long periods without permanent damage. Sexual Reproduction Water is required for transfer of the motile sperm to egg. Most antheridia are in terminal disk-shaped clusters to facilitate water capture for sperm transfer. The vase-shaped archegonia produce one egg.
