The document describes the three divisions of bryophytes: liverworts, hornworts, and mosses. Bryophytes lack vascular tissues and lignified tissues. They have rhizoids and their gametophyte generation is dominant. Liverworts include thalloid and leafy forms. Mosses include true mosses like Polytrichum that have photosynthetic leaves and transport tissues. Hornworts have sunken antheridia and archegonia on their dorsal gametophyte surface and their sporophyte provides energy.
