  2. 2. PLANT KINGDOM <ul><li>Eukaryotic </li></ul><ul><li>Multicellular </li></ul><ul><li>Photoautotrophs </li></ul><ul><li>Chloro a and b, carotenoids </li></ul><ul><li>Cell wall- cellulose </li></ul><ul><li>starch </li></ul>
  3. 3. Kingdom Plantae <ul><li>Nonvascular Plants: No water-conducting cells (xylem). </li></ul>1. Division Bryophyta (mosses and liverworts). <ul><li>Vascular plants: Xylem tissue, true roots, stems & leaves. </li></ul>Pteridophytes: Spores but no seeds 2. Division Psilophyta (Psilotum or whisk fern. 3. Division Lycophyta (club mosses). 4. Division Sphenophyta (horsetails). 5. Division Pterophyta (ferns). <ul><li>Spermatophytes: Seed Plants </li></ul><ul><ul><ul><li>Gymnosperms--Naked Seeds </li></ul></ul></ul><ul><li>6. Division Cycadophyta (cycads). 7.
