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

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

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

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

20. Plasmodium vivax

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

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

24. Paramecium

25. Paramecium

27. Vorticella

28. Stentor

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

30. 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

31. Dinoflagellates

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

33. Vaucheria

34. Diatoms

35. Division Euglenophyta • Chlorophylls a and b • carotenoids and xanthophylls • Paramylon starch • pellicle
