  1. Topic: Classification Aim: Explain the characteristics of some different protists. Do Now:List the 6 kingdoms that exist. http://www.brainpop.com/science/diversityoflife/sixkingdoms/ HW: Textbook assignment about the different types of protists is due tomorrow!

  2. Review: Identify the kingdom described. • Multi-cellular and autotrophic • Unicellular, eukaryotic, autotrophic or heterotrophic • Multi-cellular and heterotrophic • Multi-cellular, absorb digested food from the environment • Unicellular, prokaryotic, live in extreme environments • Multi-cellular, heterotrophic, ingest food • Unicellular, prokaryotic, most are beneficial, some are harmful

  3. Ameba/ Amoeba

  4. Heterotrophic

  5. Pseudopods: extensions of cytoplasm • to ENGULF food • to move around

  6. pseudopods

  7. Phagocytosis: process in which pseudopods ENGULF food • Vacuole and lysosome fuse together to digest food

  8. food vacuole pseudopods

  9. Cyclosis: used for transport & locomotion

  10. food vacuole • Contractile vacuole: contracts to release extra water pseudopods Contractile vacuole

  11. - Live in freshwater & too much water diffuses in

  12. FOOD VACUOLE CELL MEMBRANE NUCLEUS PSEUDOPOD CONTRACTILE VACUOLE

  13. Paramecium

  14. Heterotrophic Oral groove: “mouth” Anal pore: opening in cell membrane to expel waste

  15. gullet Oral groove Anal pore

  16. Vacuole

  17. Cilia: hair-like projections covering the cell used for: • Movement • Sweeping food into the oral groove

  18. cilia Oral groove Anal pore

  19. Contractile vacuole

  20. cilia Oral groove Anal pore Contractile vacuole

  21. cilia food vacuole gullet food vacuole Oral groove nucleus Anal pore Contractile vacuole

  23. Let’s summarize… • What kind of nutrition is used by protists such as ameba and paramecia? • Explain how ameba and paramecia ingest food. • Once food is ingested, explain how it is digested. • How do ameba and paramecia maintain water balance?

  24. Review: Ameba ingest large pieces of food by the process of (1.) Diffusion (2.) Osmosis (3.) Phagocytosis (4.) Respiration

  25. Once food is ingested by a paramecium, the food is surrounded by a (1.) ribosome (2.) vacuole (3.) golgi body (4.) nuclear membrane

  26. A paramecia uses ___ for movement and capturing food. (1.) pseudopods (2.) flagella (3.) teeth (4.) cilia

  27. The process which moves cytoplasm around the protist is known as (1.) diffusion (2.) osmosis (3.) cyclosis (4.) locomotion

  28. Some protists remove excess water with the help of (1.) lysosomes (2.) contractile vacuoles (3.) oral grooves (4.) food vacuoles

  29. In paramecia, wastes are expelled through the (1.) oral groove (2.) anal pore (3.) lysosome (4.) contractile vacuole
