claimThe first bryophytes, specifically liverworts, likely appeared during the Ordovician period, approximately 450 million years ago.

claimBryophytes are defined as seedless, non-vascular plants that began the colonization of land.

claimBryophytes are the closest extant relatives of early terrestrial plants.

claimBryophytes are non-vascular plants that lack specialized cells for the transport of water and nutrients.

claimBryophytes generally lack lignin and tracheids, which are xylem cells specialized for forming conduits to conduct water.

claimBryophytes are commonly called nonvascular plants, although the term non-tracheophyte is more accurate.

claimThe sporophyte, which is the diploid organism in bryophytes, is barely noticeable.

claimBryophytes possess a sporangium, which is a multicellular sexual reproductive structure that is absent in the majority of algae.

measurementThere are more than 25,000 species of bryophytes currently in existence.

claimBryophytes circulate water and nutrients inside specialized conducting cells rather than using tracheids.

claimIn bryophytes, all conspicuous vegetative organs, including photosynthetic leaf-like structures, the thallus, the stem, and the rhizoid, belong to the haploid gametophyte organism.

claimBryophytes are dependent on water for reproduction and absorb moisture and nutrients through the gametophyte surface.

claimAll nonvascular embryophytes are classified as bryophytes.

claimBryophytes are divided into three phyla: the liverworts (Marchantiophyta), the hornworts (Anthocerotophyta), and the mosses (Bryophyta).

claimThe lack of roots and reinforced conducting cells limits bryophytes to small sizes.
