For one, the … 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.
