  1. Welcome to the Exciting World of Protists… Animal-like Protists Plant-like Protists Fungus-like Protists

  2. SC ScienceStandard(s) Addressed: • Standard 7-2: The student will demonstrate an understanding of the structure and function of cells, cellular reproduction, and heredity. • Indicator Addressed- 7-2.3 Compare the body shapes of bacteria and the body structures that protists (euglena, paramecium, amoeba) use for food gathering and locomotion.

  3. Protist Diversity • 200,000 species come in different shapes, sizes, and colors • All are eukaryotes – have a nucleus and membrane-bound organelles

  4. Protozoans Animal-like Protists

  5. Protozoans • Unicellular – made up of one cell • Heterotrophs – they eat other organisms or dead organic matter • Classified by how they move

  6. Phyla of Protozoans Amoebas Flagellates Ciliates Sporazoans

  7. Amoebas: the blobs • No cell wall • Move using pseudopods – plasma extensions • Engulf bits of food by flowing around and over them

  8. Flagellates: the motorboats • Use a whip-like extension called a flagella to move • Some cause diseases • Water-borne diarrhea  Giardia • African Sleeping Sickness Trypanasoma (Vector: Tsetse Fly)

  9. Our Example: Euglena

  10. Ciliates: the hairy ones • Tiny hairs called cilia are used for locomotion and feeding • Cilia beats in a synchronized pattern to cause movement

  11. Our Example: Paramecium

  12. As an Aside…

  13. Sporazoans: the parasite • Non-motile - Do not move • Live inside a host • One type causes malaria • Plasmodium

  14. Malaria in red blood cells

  15. The End 
