Bryophyte, the traditional name for any nonvascular seedless plant—namely, any of the mosses (division Bryophyta), hornworts (division Anthocerotophyta), and liverworts (division Marchantiophyta). Most bryophytes lack complex tissue organization, yet they show considerable diversity in form and ecology. They are widely distributed throughout the world and are relatively small compared with most seed-bearing plants.

Vascular plants (tracheophytes) differ from the nonvascular bryophytes in that they possess specialized supporting and water-conducting tissue, called xylem, and food-conducting tissue, called phloem. The xylem is composed of nonliving cells (tracheids and vessel elements) that are stiffened by the presence of lignin, a hardening substance that reinforces the cellulose cell wall.
