The division Bryophyta comprises the nonvascular complex plants, i.e. complex plants without vascular tubes or to circulate liquids around their bodies. There is a great deal of disagreement with the classication level of these plants, with some workers elevating the three classes shown in the table to division level.
These plants are generally gametophyte-oriented; that is, the normal plant is the haploid gametophyte, with the only diploid structure being the sporangium in season.
Bryophytes are considered to be the most primitive division of true plants. The three classes of bryophytes are the mosses, liverworts and hornworts. It is believed that bryophytes evolved from green algae and all other plants evolved from them.
The study of bryophytes is called bryology.
