3. KINGDOM PROTISTA (most diverse kingdom) Aquatic All are eukaryotic Unicellular or multi- cellular Microscopic or very large Heterotrophic or autotrophic Plant-like, animal-like or fungus-like

4. PROTOZOA (singular: protozoan) Animal-like protists All are unicellular heterotrophs Classified by how they move Move by means of cilia, flagella, pseudopods Reproduce asexually - (Binary fission) - some sexually (Conjugation) Some are parasitic sporozoans

5. AMOEBAS Protozoans with pseudopods “False foot” Extensions of cytoplasm Aid in movement & feeding Shapeless

6. Phagocytosis

7. FLAGELLATES Flagella - long, whip-like hairs

8. CILIATES Cilia - tiny hairs Includes: Paramecium Vorticella Stentor

10. SPOROZOANS Produce spores Parasitic protozoans Malaria Sleeping sickness Trichomonas Plasmodium (causes Malaria)

13. ALGAE Plant-like protists Lack true leaves, roots and stems Autotrophs Produce more than half the earth’s oxygen

14. ALGAE Photosynthesizing protists Contain chlorophyll Includes: Red, green, brown, golden algae Diatoms - contain silica Dinoflagellates DIATOMS

15. Spirogyra Volvox Mixed green algae

16. Algae in Your Foods “Seaweed” Foods: broth, soups, seasons rice, added to salads, wrapped with sushi, rice crackers, flavors and preserves - noodles, bread, cheese, chocolate milk, creamed products, dairy desserts, dry mixes, evaporated milk, frozen food, fruit juice, ice cream, pudding, pasta, sauces and gravies, syrup, Anti drying agent; food stabilizing and consistency, thickens, uniform texture Red Algae Gel forming, suspending, emulsifying, film forming, thickens Brown Algae

17. RED ALGAE BROWN ALGAE

18. DIATOMS

19. Dinoflagellates: known as “fire algae” (cause red tides)

20. FUNGAL PROTISTS Unlike fungi, fungus-like protists are able to move and lack chitin in their cell walls. Slime molds

21. FUNGAL PROTISTS Slime molds Water molds Downy mildews

22. SLIME MOLD WATER MOLD
