Presentation Transcript

  1. Protists and Fungi

  2. Characteristics of Kingdom Protista • Most diverse group • Eukaryotic cells • Some autotrophs, some heterotrophs • Unicellular and multicellular

  3. Kingdom Protista Types • Algae-Plant like Protists, autotrophs • Protozoans-Animal like Protists, all unicellular, heterotrophs • Fungus like Protists- move at some point in their lives

  4. Algae • Classified by color • Euglenoids • Golden Algae • Green Algae • Brown Algae • Red Algae • Fire Algae

  5. Euglenoids • Autotrophic and heterotrophic • Flagella- hunt like an animal • Chloroplasts- make own food • like plant

  6. Golden Algae Diatoms- two shells

  7. More Diatoms

  8. Green Algae Unicellular and multicellular Contain chlorophyll Plant ancestor Examples: spirogyra, ulva- sea lettuce, volvox- colonial algae

  9. Green Algae Spirogyra

  10. Green Algae

  11. Brown Algae • Seaweed and kelp • Has air bladder- gas-filled structures that keep algae floating near the surface for photosynthesis

  12. Red Algae Feathery and fragile bodies Live in deep oceans

  13. Fire Algae Dinoflagellates Bioluminescence- glow when disturbed in the water

  14. Fire Algae Red tide- uncontrolled growth (algal bloom) of dinoflagellates. Release poisons that kill fish

  15. Protozoans • Classified by method of movement • Rhizopods • Ciliates • Flagellates • Sporozoans

  16. Rhizopods Amoeba Move by pseudopodia- “false feet”- extends plasma membrane around prey forming a pocket

  17. Label the parts of the amoeba • Contractile vacuole- used to pump out excess water Nucleus Plasma membrane Contractile vacuole Food particle engulfed by pseudopodia Food vacuole Pseudopodia cytoplasm

  18. Ciliates Move by beating cilia Stentor Paramecium

  19. Ciliates Contractile Vacuole Cilia micronucleus macronucleus Oral groove Anal pore

  20. Flagellates Move by flagella Trypanasoma

  21. Sporozoans No method of movement Must live in food supply to survive Many are parasitic

  22. Fungus Like Protist Plasmodium- colorful slime molds found oozing on rotting logs in forests Slime mold

  23. Kingdom Fungi Review • Classified by the shape of the structure that holds the spores • Saprophytes- feed on dead matter • Some parasites • Stationary like plants/Heterotrophic like animals • Absorb food through cell walls

  24. Bread mold Bread Mold-Rhizopus Sporangia Black Mold -Stachybotris

  25. Rhizopus- Bread Mold spores sporangium sporangiophore Hyphae mycellium

  26. Mushrooms

  27. Mushroom development gills basidia cap spores button stipe

  28. Yeast important in brewing and baking, make Penicillium

  29. Lichens Fungus and algae Mutualistic relationship-algae provides food and fungus provides protection and moisture
