1. Kingdom Protista 3 GROUPS OF PHYLA: ANIMAL-LIKE, PLANT-LIKE AND FUNGAL-LIKE PROTISTS ARE: UNICELLULAR, COLONIAL, OR MULTICELLULAR; EUKARYOTIC; MOSTLY HETEROTROPHIC; NOT DISTINCTLY PLANT OR ANIMAL

2. Animal-Like Protists- heterotrophic  Animal like protists are categorized according to their method of movement.  Phylum Sarcodina- pseudopods  Phylum Mastigophora/Zoomastigina- flagellum  Ciliophora- cilia  Sporozoa- no movement (just through spores)

3. Phylum Sarcodina  Free living (freshwater, saltwater, soil)  Some are animal parasites  Can move with the aid of a pseudopod (false feet)- move by cytoplasmic extensions and retractions of the pseudopod  Engulfs food  Ex. amoeba

4. Phylum Zoomastigina  Live in freshwater or salt water  Parasitic and disease-causing  No sexual reproduction, mostly use fission (asexual)  Form cysts and spread from host to host  Ex. Trypansoma (sleeping sickness)

5. Phylum Ciliophora  Most complex of this kingdom; most advanced  Cilia on body (hair-like projections) help organism ‘swim’  Reproduce asexually through binary fission and sexually by conjugation  Ex. paramecium

6. Phylum Sporozoa  Need host to move around  Ex. Plasmodium that causes Malaria  CYCLE: mosquito  human  liver  red blood cells  blood cell breaks  spreads to more cells

7. Plant-Like Protists  Often referred to as algae  Can exhibit characteristics of both plants and animals  Are plant-like because they have cell walls and chlorophyll  Reproduction can be sexual or asexual

8. Phylum Chlorophyta  The Green Algae

9. Phylum Pyrrophyta  Fire-algae  Produce light  dinoflagellates

10. Phylum Rhodophyta  Red Algae

11. Phylum Chrysophyta  Golden Brown Algae

12. Phylum Phaeophyta  Brown Algae  Kelp

13. Phylum Euglenophyta  Animal and plant-like features:  Chloroplasts  Engulfs food  Flagella  Ex. euglena

14. Fungal-like Protists Phylum Myxomycophyta/Myxomycota  Called slime molds  Body is called plasmodium  Constantly changing shape
