2. Kingdom Protista Chapter 20 “Diversity is the Key”

3. What is a protist? Unicellular Eukaryotic Classified into 3 general categories Animal like Plant like Fungus like *Based on mode of metabolism

4. Animal Like Protists Classified by movement 1. Zooflagellates 2. Sarcodines 3. Ciliates 4. Sporozoans

5. Zoomastigina Euglena, Trypanasoma “Flagellates” move by using a whip like tail Have red pigmented eyespot for detecting light

6. Sarcodina Amoeba proteus Move and eat using psuedopods Flexible and active Fresh and Salt Water

7. Ciliophora Paramecium/Vorticella Move by using cilia Macronucleus-day to day Micronucleus- chromosomes and DNA Stentor to the right  Fresh and Salt Water Contractile Vacuoles to remove water

8. Sporozoa Plasmodium Reproduce using spores Parasites, carried by insects Plasmodium causes malaria

9. Plant Like Protists Classified by color 1. Diatoms 2. Dinoflagellates 3. Red Algea 4. Brown Algea 5. Green Algea

10. Bacillariophyta Diatoms Contain carotenoids for their gold pigments Have geometric shells that are cell walls made of silica Marine and Freshwater Many Uses (glass,toothpaste, soil component)

11. Pyrrophyta Dinoflagellates Double flagella Can secrete toxins in Red Tide (found in shellfish) Not all toxic, give off light

12. Rhodophyta Red Algae Absorbs blue wavelengths of light allowing them to live deeper in the water column Helps build coral reefs

13. Phaeophyta Brown algae/Kelp Largest of the algae Can grow up to 60 m Closely related to land plants in structure Mostly marine

14. Giant Kelp

15. Chlorophyta Volvox, Ulva Most numerous of all plantlike protists Fresh and marine water, green algae Most attach to rocks Ulva shown to the right 

16. Fungus Like Protists Classified by reproduction 1. Cellular Slime Molds 2. Acellular Slime Molds 3. Water Molds

17. Acrasiomycota Cellular Slime Molds Move like amoeba Reproduce with spores from “fruiting body” and undergo cell division? When food runs out, spores are released

18. Myxomycota Plasmodial Slime Molds Considered a giant bag of cytoplasm with many nuclei Reproduce by spores from “sporangia” Extend vein like structures to absorb decaying food Can grow several meters

19. Oomycota Water molds and downy mildews Saprophytic or Parasitic Thrive on detritus in the water Make “hyphae” or thin filaments  Alternate b/t sexual and asexual reproduction
