Associations of Bryophyes with mychorrizae are common. . Impact on Structure Bryophytes lack vascular tissues so Bryophytes must absorb all water and nutrients at the surface and pass them from cell to cell. A few have modified water transport cells, call hydroids , and a few have solute conducting cells, called leptoids , but this is rare. Depending on cell to cell diffusion for transport places size restriction on Bryophytes. Gemmae propagules Fragmentation Gametophyte generation is the predominant and assimilative stage.
Mosses attach to their substrate with multicellular rhizoids .
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.
