*bryophyta are called the amphibians of plants because they live on soil and reproduce in water.
*it includes mosses and liverwort.
*they play an important role in plant succession on bare rocks.
*plant body is different from algae, it is thallus like and prostrate or erect, and attached to the substratum by unicellular or multi-cellular rhizoids.
*the main plant body of bryophytes are haploid, it produces gametes, hence it is called gametophytes.
*sex cell in bryophytes are multicellular.
*male sex organ is called antheridium, produces biflagellate antherozoids.
*female sex organ is called archegonium,which is flask-shaped , produces single egg.
*fusion of gametes take place in water and forms zygote.
*zygote does not undergo reduction division and forms multicellular body called sporophyte.
*sporophyte is not free living, it is attached to gametophyte for food.
*sporophyte undergo meiosis division and forms haploid spores,these germinate to produce gametophytes.
*some mosses are edible by some animals.
*some bryophytes are used as fuel.
*mosses along with lichen are the first organism to colonise on rock, they decompose rock and make it suitable for growth of higher plants.
