Let me share with you a difference between liverworts and mosses.
Aspect | Liverworts | Mosses |
Structure of gametophyte | Thallus (flat and ribbon-like) or leafy | Leafy structures with stems and leaves |
Rhizoids | Single-celled or multi-cellular, often scattered on the lower surface | Single-celled, often clustered on the lower surface |
Spore capsule | May be elevated or embedded in the thallus, lacks a seta (stalk) | Typically elevated on a seta (stalk), capsule may have a peristome for spore release |
Sporophyte dependency | May be more independent of the gametophyte | Often more dependent on the gametophyte for nutrients and water |
Reproduction | Can reproduce through spores and gemmae cups (asexual reproduction) | Reproduce through spores and some species also produce specialized structures (gemmae cups) for asexual reproduction |
Habitat | · Soil · Rocks · Tree bark | · Moist woodlands · Rocks · Soil |
Leaf arrangement | Simple, may lack differentiation into distinct stems and leaves | Distinct leaves arranged spirally or in whorls along the stem |
Capsule Dehiscence | Dehiscence can be irregular, without a well-defined mechanism | Often dehisce through a well-defined mechanism, such as the peristome teeth |
Examples | · Marchantia · Riccia · Pellia | · Polytrichum · Sphagnum · Bryum |
