  1. Kingdom Protista Protists- the hodge- podge group

  2. Basics • Eukaryotic • 3 groups- animal like -Protozoans plant like- Algae fungi like- Slime molds Evolved from a symbiotic relationship: 1 prokaryote engulfed another (like a mitochondrial or chloroplast like cell) ENDOSYMBIOSIS

  3. Protozoans- animal like

  4. Pseudopods stream in different directions to make amoeba move. • Single celled • Pseudopods surround food and engulf it

  5. Giardia • Can cause giardiasis. • Usually from contaminated water. • Called backpackers diarrhea

  6. Paramecium • Use cilia to sweep food into oral groove and then digest in the gullet. • Has 2 nuclei- I macro and 1 micro

  7. Plasmodium • Causes malaria • Lives in gut of mosquito • Mosquito bites human • Injects some spores- they germinate and live in the blood

  8. ALGAE-Plant like • Contain chlorophyll or other pigment • Can be unicellular, multicellular or colonial • 7 types

  9. Euglenophyte: Euglena • Unique because they can do photosynthesis and ingest food(heterotrophic). • Has an EYESPOT which helps detect light so it can swim towards it to photosynthesize • Has a flagella for movement • Pellicle- thick outer covering

  10. Chrysophyte:Golden Algae • Many unicellular • Some colonial • Gold colored chloroplast

  11. Diatoms • Contain chlorophyll • Photosynthetic • Shell made of SILICA- used for abrasives in cleansers like toothpaste • Also called phytoplankton

  12. Dinoflagellates • Cell wall contains cellulose • Contain chlorophyll • Also have another pigment called carotenoid(orange color) • Cause Red Tide- due to overgrowth in the ocean. Produces a toxin that is harmful to sea life and humans

  13. Red Algae • Phylum Rhodophyta • Multicellular • Marine sea weed • Has no roots, stems, or leaves • Main structure called a thallus • Has Chlorophyll a and phycobilins that help harvest light at deep depths.

  14. Brown Algae • Phylum Phaeophyta • Multicellular • Contain chlorophyll and a brown pigment- FUROXANTHIN • Kelp • Have air bladders to keep them afloat

  15. Green Algae • Phylum Chlorophyta • Most live in fresh water • Can be unicellular or multicellular Spyrogyra-multicellular • Volvox is a colonial green algae

  16. Uses for Algae • Base of the food chain • Produce O • Sushi:nori • Smoothener in foods like ice cream and pudding • Industrial uses: plastics, waxes, deodorant, paint, agar( material used to grow bacteria)

  17. Fungi like – Slime Molds and Water Molds • Live in moist, cool environment • Watery molds- Oomycota
