  1. Kingdom: Protista The most diverse of the 5 kingdoms Can be animal-like, plant-like or fungus-like. More than 200,000 species Classified by the different shapes, sizes & colors

  2. Known as protozoans Unicellular Heterotrophs Feed on other organisms Grouped by way they move. Animal-Like Protists

  3. Cilia: hair like particles. Protozoans Move #1

  4. Protozoans Move #2 • Flagella: whip like tail

  5. Protozoans Move #3 • Pseudopodia: cytoplasm extensions

  6. Protozoans Move #4 • Non-motile have no way of capturing food so they live as parasites.

  7. No cell walls Pseudopodia (cytoplasm feet): means for movement Engulfs bits of food Blob like-change shape constantly Amoeba outer cells are made of Calcium Carbonate Amoeba: Phylum Sarcodia Some amoebas live in salt water, Few are found in freshwater

  8. Amoebas Radiolarian Foraminiferan

  9. Have 1 or more flagella Some species are parasites/ others helpful. ie: termites. ie: African Sleeping Sickness Flagellates: Phylum Zoomastigina

  10. African Sleeping Sickness • Transmitted by tsetse fly (lives only in Africa) • Fever, lethargy, mental deterioration, coma

  11. Tsetse fly

  12. Trypanosoma cruzi • Chagas’ Disease • Transmitted by “kissing bugs” –cone bugs • Fever and severe heart damage

  13. Leishmania donovani • Transmitted by sand flies • Disfiguring skin sores • Can be fatal

  14. Move by beating cilia Found in every kind of aquatic habitat Ponds, streams, oceans & sulfur Ex: Paramecium Ciliates: Phylum Ciliophora

  15. Paramecium Parts

  16. Parasitic Non-motile Produce many spores Best known member:Plasmodium Causes malaria-transferred by mosquito’s Sporozoans: Phylum Sporozoa

  17. Plasmodium Transferred by mosquitoes Kills 2-4 million people/yr. Treatments now Malaria:

  18. Life cycle

  19. Plant-Like Protists • Multi-cellular photosynthetic protist • 1. Look like plants – no roots, stems/leaves • 2. Contains chlorophyll • 3. Classified by pigment colors

  20. Algae classified by 6 phyla • 3: euglenoids, diatoms, & dinoflagellates • 3: unicellular members: Green, Red & Brown Algae

  21. Euglenoids: Phylum Euglenophyta • Unicellular • Plant like: chlorophyll • Animal like: responsive movement • 1 or 2 flagella

  22. Euglena Body Eye Spot detects enough light to find food Whip-like tail Makes Green

  23. Shells: small pillbox w/ lids, made of silica Make up large number of plankton When die: sinks to ocean floor Dredge/Mine Toothpaste, paints Pavement lines Diatoms: Phylum Bacillariophyta

  24. Diatoms

  25. Dinoflagellates: Phylum Dinoflagellata • Also called: Spinning Algae/Fire Algae • Look like helmets & suits of armor • Cause red tides: produce toxins • Oceans turn red/orange • Kills tons of fish

  26. Red Tides

  27. Red Algae: Phylum Rhodophyta • Red seaweed • Tropical waters along rocky coast • Holdfast to attach • Deep waters w/ lots of pigments

  28. Brown Algae: Phylum Phaeophyta • 1500 species all live in salt water • Kelp most common • Anchor w/ holdfast • Body of kelp called thallus • Thallus 3 parts: holdfast stipe blade

  29. Brown Algae • The largest and most complex of brown algae are kelp.

  30. Green Algae: Phylum Chlorophyta • Most diverse. 7000 species • Most species live in fresh water • Others: ocean, moist soil tree trunks

  31. Fungi-Like Protists • Groups of slime molds & Water Molds • Reproduce: Form delicate structures on food supplies • Obtain energy by decomposing organic material.

  32. Slime Molds • Animal-like & Fungi-like • Classified by reproduce • Beautiful colors • Live in cool moist shady places

  33. 2 major types of Slime Molds 1. Plasmodial Slime Mold: phylum: Myxomycota 2. Cellular Slime Mold phylum: Asrasiomycota

  34. Water & Downy Moldsphylum Oomycota • Live in water or moist places • Appear fuzzy & white on decaying material
