    • KINGDOM PLANTAE
    • PLANT KINGDOM
      • Eukaryotic
      • Multicellular
      • Photoautotrophs
      • Chloro a and b, carotenoids
      • Cell wall- cellulose
      • starch
    • Kingdom Plantae
      • Nonvascular Plants: No water-conducting cells (xylem).
      1. Division Bryophyta (mosses and liverworts).
      • Vascular plants: Xylem tissue, true roots, stems & leaves.
      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).
      • Spermatophytes: Seed Plants
          • Gymnosperms--Naked Seeds
      • 6. Division Cycadophyta (cycads). 7. Division Ginkgophyta (maidenhair tree). 8. Division Gnetophyta (mormon tea & Welwitschia). 9. Division Coniferophyta (conifers).
          • Angiosperms--Seeds Enclosed In A Fruit
      • 10. Division Anthophyta (flowering plants)
    • Non vascular plants
    • Division Bryophyta
      • lack complex vascular tissue
      • No true roots, stem and leaf
      • Rhizoids
      • sperms are flagellated
      • Sporophyte is dependent on the gametophyte
    • Sporangium or capsule Seta or stalk *foot
    •  
    • Seedless Vascular Plants
    • Seedless Vascular plants
      • include ferns, whisk ferns, club mosses, and horsetails
      • do not produce seeds
      • gametophyte and sporophyte are independent
      • true roots, stems, and leaves
    •  
      • Microphyll
      • Macrophyll
      • Sporophyll
      • Sporangia
      • Homosporous
      • Heterosporous

        • Selaginella, Lycopodium
      • Division Sphenophyta
        • Equisetum or horsetails
      • Division Pterophyta (ferns).
    • Lycopodium (Club moss) strobilus

    • Seed Plants
    • Seed Plants
      • Vascular tissues – X and P
      • Seeds
      • Gymnosperms and Angiosperms
      • Reduced gametophyte
    • Gymnosperms
      • have naked seeds
      • Do not have flowers
      • A. Division Cycadophyta (cycads). B. Division Ginkgophyta (maidenhair tree). C. Division Gnetophyta D. Division Coniferophyta (conifers).
    • Division Cycadophyta Cycas revoluta
    •  
    •  
    •  
    • Division Coniferophyta
      • the largest group of gymnosperms
      • pine, cedar, spruce, fir, and redwood trees
      • naked seeds produced in cones
      • Evergreen leaves
      • needle-like leaves- adapted for dry conditions
      • Pinus insularis- Benguet pine
      • Pinus merkusii- Mindoro pine
    • Male cone - microstrobilus Seed cone - megastrobilus
