1. Kingdom Protista Groups Protozoan and Algae

4. Systematists have split protists into many kingdoms Protists are the most diverse of all eukaryotes –Cell structure –Nutrition –Motility –Life cyles –Habitats

5. General characteristics Stuck in group First eukaryotic Largest group of 6 kingdoms Multicellular and unicellular Reproduce sex and asexually Divide by mitosis Complex cilia and flagella Autotrophic and heterotrophic

6. Two Major Groups Protozoans Algae “heterotrophic”“autotrophic”

7. Importance of studying Protists? They are everywhere there is water! Cause diseases Part of food chain Photosynthetic…what is important product? Recycle nutrients…N, C and P

8. 4 major groups of protozoans 1.Sarcodina 2.Ciliophora 3.Zoomastigina (Mastigophora) 4.Sporozoa

9. Sacrodina Amoeba eating a ciliate Concerns: –Amboeic dysentery: bloody diarrhea, vomiting, extreme stomach cramps, transmitted by contaminated food or water

10. How do Sacrodina Move? Pseudophodia

11. Sacrodina Special Characteristics Asexual or sexual Contractile vacuole Eat by Phagocytosis –See animation Unicellular Habitat –Ponds –Lakes Only in Fresh water http://highered.mcgraw- hill.com/sites/9834092339/student_view0/c hapter4/animation_- _cytoplasmic_streaming.html

12. Ciliophora “The Ciliates” paramecium

13. How do Ciliophora move? Cilia

14. Special Characteristics Ciliophora Live in Fresh and salt water environments Respond to chemicals Trichocyst: help capture prey Micronucleus (genetic exchange thru conjugation) Contractile vacuole – –Store and remove water

16. Ciliophora Examples –Bursaria –Didinium –Paramecium

17. Mastigophora Move by flagella Habitat: Fresh or salt water Some are parasitic –Most live on bodies of other organisms

18. Mastigophora VolvoxEuglena

19. Examples of Mastigophora Trichonympha –Termites: digest cellulose…can we digest it?? Giardia –Fever Fatigue, fatal –Transmitted thru water/food from the protist: Giardia lamblia African sleeping sickness –Fever, lethargy –Bite from a tsetse fly

20. Sporazoa

21. No movement Produced spores that withstand harsh conditions Habitat: All parasitic

22. Examples of Sporazoa Cryptospordium –Cryptosporidiosis (diarrhea) Toxoplasmosis –Toxoplasma species Malaria –destroys RBC –High fever –Delirium –Sweats and chills
