  1. Kingdom Protista

  2. Kingdom Protista • Is considered to be the “junk drawer” kingdom since it’s very diverse. • All are eukaryotes (with nuclei) that live in moist surroundings.

  3. There are ? types of protists. 3

  4. Animal-like Protists (Protozoans) • Move place to place to obtain food • Single-celled (unicellular) • There are 4 types of Protozoans:

  5. 1. Sacrodines • Ones with psuedopods(pseudo=false, pod=foot) • These organisms allow their cell membranes to bulge out so they can move.

  6. 1. Sacrodines • An example is an amoeba. • Amoebas have a contractile vacuole; structure that collects extra water and expels it from cell.

  7. 2. Ciliates • Contain cilia or hair-like projections from the cell. • Example: paramecium

  8. 3. zooflagellates • Have 1-8 whip-like tails called flagella. • Example: Giardia

  9. 4. Sporozoans • Parasites that feed on cells/body fluids of hosts. • Example: Plasmodium (causes malaria)

  10. 2. Fungus-like Protists • Like fungus, fungus-like protists are heterotrophs, have cell walls, and use spores to reproduce. But unlike fungi, these guys at some point can move.

  11. Fungus-like protists • Examples: • water molds (grows as tiny threads for a fuzzy covering), downy mildews, and slime molds (bright colored, feed on decaying plants.

  12. 3. Plant-like Protists Algae-all are autotrophs like plants, most O2 comes from these organisms, they vary in size.

  13. Plant-like Protists • Euglenoids – green unicellular algae found in freshwater. They have long flagellum. • Dinoflagellates – unicellular algae covered in “stiff plates”, 2 flagella, many glow in dark

  14. Plant-like Protists • Diatoms – unicellular with glass-like walls, support the aquatic ecosystem.

  15. Plant-like Protists • Green algae – uni- and multicellular, green pigments.

  16. Plant-like Protists • Red algae – almost all are multicellular seaweeds, some can live below 260 meters in the ocean. Carrageenan comes from red algae and is used in making ice cream and conditioner.

  17. Plant-like protists • Brown algae – Giant kelps, brown, yellow, and orange pigments. • Orange pigments help make salad dressing and pudding.
