2. Protists

3. Unicellular (single-celled) organisms with a nucleus

4. 3 Types of Protists

5. 1.Animal-like

6. 3 Types of Protists 1.Animal-like 2.Plant-like

7. 3 Types of Protists 1.Animal-like 2.Plant-like 3.Fungus-like

8. Animal-like Protists Also called “protozoa”

9. Animal-like Protists Also called “protozoa” (“first” “animal”)

10. Animal-like Protists Characteristics:

11. Animal-like Protists Characteristics: 1.Cells have nucleus

12. Animal-like Protists Characteristics: 1.Cells have nucleus 2.No cell wall

13. Animal-like Protists Characteristics: 1.Cells have nucleus 2.No cell wall 3.Most can move

14. Animal-like Protists Characteristics: 1.Cells have nucleus 2.No cell wall 3.Most can move 4.Heterotrophs

15. Animal-like Protists Characteristics: 1.Cells have nucleus 2.No cell wall 3.Most can move 4.Heterotrophs (can’t make own food)

16. 4 Groups of Animal-like Protists

17. 1.Sarcodines

18. 4 Groups of Animal-like Protists 1.Sarcodines 2.Ciliates

19. 4 Groups of Animal-like Protists 1.Sarcodines 2.Ciliates 3.Zooflagellates

20. 4 Groups of Animal-like Protists 1.Sarcodines 2.Ciliates 3.Zooflagellates 4.Sporozoans

21. Sarcodines - Have a pseudopod

22. Sarcodines - Have a pseudopod (false foot) - Use it to move and hunt

23. Sarcodines - Have a pseudopod (false foot) - Use it to move and hunt Examples: ameba (bloblike)

24. Sarcodines - Have a pseudopod (false foot) - Use it to move and hunt Examples: foraminiferans (shell)

25. Ciliates - Have cilia (hair-like structures)

26. Ciliates - Have cilia (hair-like structures) - Use cilia to move (like oars)

27. Ciliates - Have cilia (hair-like structures) - Use cilia to move (like oars) Example: paramecium

28. Zooflagellates - Have flagella (whip-like structure)

29. Zooflagellates - Have flagella (whip-like structure) - Use flagella to move Example: giardia

30. Sporozoans - Are parasites (require host) Example: plasmodium(malaria)

31. Malaria

33. Plant-like Protists

34. - All are autotrophs - They make their food from sunlight

35. Plant-like Protists 1.Euglena

36. Plant-like Protists 1.Euglena 2.Diatoms

37. Plant-like Protists 1.Euglena 2.Diatoms 3.Dinoflagellates

38. Euglena - Have chloroplasts - Have eyespots (light sensitive)

39. Diatoms - Have 2-part glassy shell - Used in toothpaste

40. Dinoflagellates - Have 2 flagella - Some can glow
