2. KINGDOM: PROTISTA “It’s a small world, after all...”

3. WHAT IS A PROTIST? PROTISTS : Uni- or multicellular Have a TRUE nucleus (eukaryotic) Can be heterotrophic or autotrophic LIVES IN MOIST SURROUNDINGS

4. WHY STUDY PROTISTS? PROTISTS...  ARE THE BASIS OF MANY FOOD CHAINS  Help control BACTERIAL populations by EATING THEM

5. PROTISTS ALSO...  CAN CAUSE DISEASES  ARE IMPORTANT IN HOUSEHOLD PRODUCTS

6. THREE KINDS OF PROTISTS  PLANT LIKE (are autotrophic)  ANIMAL LIKE (move to food)  FUNGUS LIKE (decomposer)

7. ANIMAL-LIKE PROTISTS  Known as PROTOZOANS  HETEROTROPHIC  UNICELLULAR  Have the ability to MOVE

8. AMOEBA

9. AMOEBA or AMEBA MOVE AND FEED USING A PSEUDOPOD OR “FALSE FOOT”

10. ANIMAL-LIKE PROTISTS AMOEBA PSEUDOPODS form when the cytoplasm moves

11. ANIMAL-LIKE PROTISTS AMOEBA AMOEBAS GET RID OF EXTRA WATER WITH A CONTRACTILE VACUOLE

12. ANIMAL-LIKE PROTISTS AMOEBA

13. AMOEBA Amoeba feed on bacteria and smaller protists

14. PARAMECIUM PARAMECIUM MOVE USING CILIA – HAIRLIKE EXTENSIONS FROM THE CELL (and now to the videotape!)

15. Check out the PARAMECIUM EATING!!

16. ANIMAL-LIKE PROTISTS PARAMECIUM Like amebas, paramecium have a contractile vacuole to remove excess water.

17. PARAMECIUM Paramecium feed on bacteria and smaller protists

18. ANIMAL-LIKE PROTISTS PARAMECIUM The movement of the cilia sweeps food into the oral groove

19. PARAMECIUM – Draw your own in your notebook and label the parts

20. ANIMAL-LIKE PROTISTS PARAMECIUM and AMOEBA Both paramecium and amebas mostly reproduce asexually by binary fission. Some paramecium can reproduce sexually by conjugation.

21. PROTOZOANS WITH FLAGELLA  Zooflagellates use flagella to move  Many are parasites  They live inside the bodies of other organisms

22. PROTOZOANS WITH FLAGELLA  Giardia is a human parasite  Causes “hiker’s disease”

23. FUNGUSLIKE PROTISTS  Are heterotrophs  Act like decomposers  Absorb their food

24. FUNGUSLIKE PROTISTS  A water mold caused the Irish potato famine in the 1840’s

25. FUNGUSLIKE PROTISTS  Slime molds live on decaying plants  Some can be seen with the naked eye

26. PLANTLIKE PROTISTS  CONTAIN CHLOROPHYLL  Uni- or multi-cellular  KNOWN AS “ALGAE”  AUTOTROPHIC

27. PLANTLIKE PROTISTS EUGLENA  UNICELLULAR  HAVE CHLOROPLASTS  Use flagella to move towards light  AUTOTROPHIC IN LIGHT EYESPOT detects light

28. EUGLENA Euglena becomes Heterotrophic IN DARK

29. GENERAL ALGAE information  MOST ARE UNICELLULAR which live in colonies  LIVE IN FRESHWATER OR SALTWATER

30. MULTICELLULAR ALGAE is called SEAWEED.

31. THREE “MAIN” COLORS OF ALGAE 1. Green Algae 2. Red Algae 3. Brown Algae

32. RED ALGAE  LIVE IN DEEP OCEAN WATERS  RED PIGMENT CAN ABSORB THE LITTLE LIGHT FOUND AT THOSE DEPTHS

34. RED ALGAE  CARRAGEENAN COMES FROM RED ALGAE  Used as a THICKENING AGENT in ICE CREAM “Yummy, yummy, yummy I got protists in my tummy”

35. BROWN ALGAE IMPORTANT FOOD SOURCE for many oceanic animals. Found in COLD water ecosystems. Can you name an animal that lives near or with brown algae?

36. BROWN ALGAE GIANT KELP FORMS LARGE UNDERWATER FORESTS, HOME TO MANY ORGANISMS
