1. Kingdom Protista Most diverse kingdom Live where ever there is moisture Difficult to classify

2. Three Major Groups Animal-like – Protozoans Plant-like – Algae Fungus-like

3. AND NOW THE……. PROTOZOANS THE ANIMAL-LIKE PROTIST

4. Animal Phyla Phylum Sarcodina ex. ameba Phylum Zooflagellata Ex. Trypanosoma Phylum Ciliophora Ex. Paramecium Phylum Sporozoa Plasmodium

5. Phylum Sarcodina Projections called psuedopods – used for movement and food gathering Amebas are shapeless/ radiolarians have a silica shell and foraminiferans have a calcium shell(build up and creates chalk) Amebas can form resistant cysts Parasitic amebas can cause dysentery(by drinking contaminated water and food) Amoeba = genus spelling Ameba = common name

6. Phylum Zooflagellata Have flagella for motility Trichonympha – lives in the gut of the termite and digests wood (mutalistic relationship) Trypanosoma – found in the saliva of the Tsetse fly/ it causes African Sleeping Sickness

7. Phylum Ciliophora Have cilia for motility Most numerous protozoan Most are harmless only a few are parasitic Examples include paramecium, vorticella, stentor

8. Phylum Sporoza All are non-motile and mostly parasitic Have complex life cycles Example = Plasmodium which is transmitted through the mosquito. It causes Malaria

9. AND NOW THE….. ALGAE PLANT-LIKE PROTIST

10. Phylum Dinoflagellata-fire algae 2 flagella/spin like “tops” Many are bioluminescent (converts chemical energy to light energy) Resp. for “Red Tide”

11. Phylum Bacillariophyta -Diatoms Unicelluar (look like a box and lid) Have silica (glass) cell walls **world’s largest producer of oxygen (Phytoplanton=floating microorganisms that provide basis of food chain and make oxygen) Float because they contain oil Useful in filters, toothpaste, silver polish, and paints because they reflect light)

12. Phylum Euglenophyta - Euglena Resemble both algae and protozoans Autotrophic and heterotropic Flagella and chloroplast Useful in sewage treatment plants (help breakdown sewage and add oxygen)

13. Phylum Chloropyta – Green algae Unicellar, multicelluar or colonies Very diverse group

14. Phylum Rhodophyta – red algae Multicelluar Warm, saltwater Live as deep as 260 meters Accessory pigments to absort light

15. Phylum Phaeophyta- brown algae Multicellar Mostly cool, saltwater Largest Protist (Giant Kelp_ Have air bladders to help them float

16. AND NOW THE FUNGUS-LIKE SLIME MOLDS

17. Three phyla- Myxomycota, Acrasiomycota, Oomycota Many produce a Plasmodium (feeding stage) and fruiting body stage (makes spores) Water molds were responsible for the the Great Potato Famine

18. ECOLOGICAL ROLES Plankton Phytoplankton (prod. Oxygen/ food) Zooplankton (predators on bacteria/decomposers/recycling)

19. DISEASES Amoebic dysentery Trypanosoma Plasmodium ??

20. Human Uses Carrageenan (thickner/food enhancer) Agar (soups/frosting/pudding) Algin Diatoms Bioindicators
