WebStomata or similar structures are necessary in land plants because the waxy cuticle blocks free-flow of gasses. Roots (or root-like structures) anchor plants to the soil and—in plants with true roots— serve as conduits for water absorption. All land plants except Bryophytes (mosses, liverworts, and hornworts) have true roots. WebIn addition, bryophytes possess dual generations (gametophytic and sporophytic phases) in their life cycle.
