  1. PROTISTS The “Little Guys”

  2. A DIVERSE KINGDOM

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

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

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

  6. Sarcodine Animations/Videos

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

  10. Zooflagellate Animations/Videos

  11. PROTOZOANS Sporozoans 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 Downy Mildews Slime Molds Water Molds
