GENERAL Bio216: Vascular Plants . Dan Skean. An introduction to the classes of the lower vascular plants with information about morphology and links to photographs of four representative species. PSILOTOPHYTA (WHISK FERNS) The subphylum Psilotophyta (Psilophyta or Psilopsida) represents the most primitive vascular plants. These plants arose in the Silurian and Devonian and are characterized by the presence of tracheids, but they lack true roots or leaves. The group is probably completely extinct, although two genera ( Psilotum and Tmesipteris , neither found in North America) are sometimes placed as members of this primitive group.

Vascular Plant Family Nomenclature: Names in Current Use James L. Reveal Professor Emeritus, Norton-Brown Herbarium, University of Maryland College Park, MD 20742-5815, U.S.A. The information presented here does not reflect the bizarre treatment of conserved family listed in App. II in the new funeral-black edition of the International Code of Botanical Nomenclature (Greuter, et al., Regnum Veg. 138). I have asked the Committee of Spermatophyta to review the curious decisions reached by the Editorial Committee for the Code believing that their treatment of numerous names will be found not to be supported by provisions in the Code Abietaceae through Lythraceae Maesaceae ...

Clicking the high-lighted key words in the text brings you to an index of links from where you can start your virtual palaeobotany tour around the world. As some groups of plants appear to be more common on the web than others, we have added some photos from our own archives to complete this selection. These photos are of course particularly recommended! Because the various researchers sometimes use different names for the same (groups of) plants, careful readers might notice some inconsistencies in the naming of the fossil plants. This also applies to the names of geological periods.

PLANTS AND THEIR STRUCTURE Table of Contents General Plant Organization Parenchyma Collenchyma Sclerenchyma ... Links General Plant Organization Back to Top A plant has two organ systems : 1) the shoot system, and 2) the root system. The shoot system is above ground and includes the organs such as leaves, buds, stems, flowers (if the plant has any), and fruits (if the plant has any). The root system includes those parts of the plant below ground, such as the roots, tubers , and rhizomes Major organ systems of the plant body. The above image (left) is from Purves et al., Life: The Science of Biology , 4th Edition, by Sinauer Associates ( www.sinauer.com ) and WH Freeman ( www.whfreeman.com ), used with permission. The above illustration (right) is from gopher://wiscinfo.wisc.edu:2070/I9/.image/.bot/.130/Intr._Plant_Body_Spring_/Primary_130_Lab_Images/Bean_whole_morphology Plant cells are formed at meristems, and then develop into cell types which are grouped into tissues . Plants have only three tissue types: 1) Dermal Ground ; and 3) Vascular . Dermal tissue covers the outer surface of herbaceous plants. Dermal tissue is composed of epidermal cells, closely packed cells that secrete a waxy cuticle that aids in the prevention of water loss. The ground tissue comprises the bulk of the primary plant body. Parenchyma, collenchyma, and sclerenchyma cells are common in the ground tissue. Vascular tissue transports food, water, hormones and minerals within the plant. Vascular tissue includes xylem, phloem, parenchyma, and cambium cells.
