They are sometimes placed in a division Lycopodiophyta or Lycophyta or in a subdivision Lycopodiophytina. They are one of the oldest lineages of extant (living) vascular plants; the group contains extinct plants that have been dated from the Silurian (ca. 425 million years ago…

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. scokeys

Web9 sept. 2024 · Lycophyte leaf phyllotaxy is species-specific, and can vary from spiral to whorled to opposite, arising independently of xylem patterns in the stem (Gola et al., 2007; Webster, 1992). According to the enation theory, lycophyte leaves arose by progressive elaboration of epidermal outgrowths, into which vascular strands later entered (Bower, … WebIn lycophyte: Life cycle.
