Document Summary
Describe four shared derived homologies that link charophyceans and land plants. (fig. 29. 2: rose-shaped complexes for cellulose synthesis, peroxisome enzymes, structure of flagellated sperm. Describe four characteristics that distinguish land plants from charophycean algae. alternation of generations and multicellular, dependent embryos apical meristems: walled spores produced in sporangia, multicellular gametangia. List and distinguish among the three phyla of bryophytes. Briefly describe the characteristics of each group. small herbaceous (nonwoody) plants. Liverworts: phylum hepatophyta: hornworts: phylum anthocerophyta, mosses, phylum bryophyta nonvascular plants. Explain why most bryophytes grow close to the ground. their tissues aren"t that thick. The bryophytes have independent ____________ as well as attached dependent _______. Describe the three traits that characterize modern vascular plants. Explain how these characters have contributed to their success on land: sporophytes of seedless vascular plants are the larger generation. The gametophytes are tiny plants that grow on or below the soil surface. *lycophyta = club mosses, spike mossees, and quillworts.
