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. 1.Multi-cellular and autotrophic 2.Unicellular, eukaryotic, autotrophic or heterotrophic 3.Multi-cellular and heterotrophic 4.Multi-cellular, absorb digested food from the environment 5.Unicellular, prokaryotic, live in extreme environments 6.Multi-cellular, heterotrophic, ingest food 7.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

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

9. pseudopods food vacuole

13. Cyclosis: used for transport & locomotion

14. Contractile vacuole: contracts to release extra water Contractile vacuole pseudopods food vacuole

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

16. NUCLEUS PSEUDOPOD CONTRACTILE VACUOLE FOOD VACUOLE CELL MEMBRANE

17. Paramecium

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

19. Oral groove Anal pore gullet

20. Vacuole

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

23. Oral groove cilia Anal pore

27. Contractile vacuole

28. Oral groove cilia Contractile vacuole Anal pore

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

32. Let’s summarize… 1.What kind of nutrition is used by protists such as ameba and paramecia? 2.Explain how ameba and paramecia ingest food. 3.Once food is ingested, explain how it is digested. 4.How do ameba and paramecia maintain water balance?

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

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

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

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

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

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