  2. Kingdom Protista • Phylum Rhizopoda • Phylum Actinopoda • Phylum Foraminifera • Phylum Apicomplexa • Phylum Zoomastigophora • Phylum Ciliophora

  3. Phylum Rhizopoda • Includes amebas • unicellular • shelled (tests) or naked • pseudopodia • no meiosis • freshwater, marine, soil

  4. Amoeba proteus Endoplasm (sol) pseudopod nucleus Ectoplasm (gel)

  5. Arcella

  6. Difflugia

  7. Entamoeba histolytica

  8. Phylum Actinopoda • Heliozoans • primarily freshwater • tests • silicas • diatoms • sand grains • Radiolarians • primarily marine • tests • silicas

  9. Heliozoans cortex medulla

  10. Radiolarian

  11. Phylum Foraminifera • Exclusively marine • multichambered • tests of calcium carbonate

  12. Myxomycota • Acellular slime molds • plasmodium • Physarum polycelphalum

  13. Acrasiomycota • Cellular slime molds • amebas • Dictyostelium discoideum

  14. Oomycota • Water molds • oogamous • Achyla & Saprolegnia

  15. Phylum Apicomplexa • Many pathogenic species • infectious cells called sporozoites • Plasmodium vivax - malaria

  16. Plasmodium vivax

  17. Phylum Zoomastigophora • Use flagella to move • solitary or colonial • some pathogenic • Trypanosoma - African Sleeping Sickness

  18. Phylum Ciliophora • Ciliates • macro and micronucleus • fresh & salt water • Paramecium, Stentor, Vorticella

  19. Paramecium

  21. Vorticella

  22. Stentor

  23. The Algae • Division Pyrrophyta • Division Chrysophyta • Division Euglenophyta • Division Chlorophyta • Division Phaeophyta • Division Rhodophyta

  24. Division Pyrrophyta • Chlorophylls a and c • carotenes & xanthophylls • amylose starch • cellulose in those with shells (some naked) • marine & freshwater • 2 flagella • red tides, ciguterra, bioluminescence

  25. Dinoflagellates

  26. Division Chrysophyta • Chlorophylls a and c • carotenoids & xanthophylls • leucosin and laminarin • silica or pectin compounds • freshwater & marine • 1 or 2 flagella
