1. PROTISTS The “Little Guys”

3. BUT… There are some general characteristics they all share: Unicellular (made of one cell) Unicellular (made of one cell) Eukaryotes (have a nucleus) Eukaryotes (have a nucleus) Live in moist environments Live in moist environments

4. Protists Animal-like Protozoans Plant-like Algae Fungus-like Heterotrophs Classified by how they move Autotrophs Have cell walls Heterotrophs Have cell walls -Sarcodines -Ciliates -Zooflagellates -Sporozoans

5. PROTOZOANS Move using PSEUDOPODS (“false feet”), bulges of the cell membrane Example: AMOEBA Pseudopod

6. Sarcodine Animations/Videos

7. PROTOZOANS Move using CILIA, tiny hair-like projections that move in a wavelike motion, acting like oars Example: PARAMECIUM Cilia

8. Ciliate Animations/Videos

9. PROTOZOANS Move using FLAGELLA, a long, whip-like structure Example: EUGLENA Flagella

10. Zooflagellate Animations/Videos

11. PROTOZOANS Parasites that feed on the cells and fluids of their host Example: PLASMODIUM (causes malaria) Transmitted by mosquitoes

12. ALGAE Diatoms Dinoflagellates Green Algae Brown Algae Red Algae

13. FUNGUS-LIKE Slime Molds Water Molds Downy Mildews
