  1. Kingdom Protista!

  2. Kingdom Protista • Contains the MOST diverse organisms of all the kingdoms! • ALL are eukaryotes • Animal-like protists: Protozoa • Plant-like protists: Algae • Fungus-like protists

  3. Protozoans: Animal-like Protists • Unicellular heterotrophs that move in a variety of ways • 4 groups: • Amoebas • Flagellates • Ciliates • Sporozoans

  4. Protozans: Amoebas • Form pseudopods to move and feed • Ex: amoeba

  5. Protozoans: Cilliates • Move by beating cilia that cover the cell • Ex: parimecium

  6. Protozoans: Flagellates • Move by whipping flagella from side to side • Ex: giardia

  7. Protozoans: Sporozoans • Parasites • Produce spores to reproduce • Ex: plasmodium—causes malaria malaria life cycle

  8. Algae: Plant-Like Protists • Photosynthetic autotrophs may be uni- or multicellular • Produce half of the world’s oxygen! • 2 main groups: unicellular and multicellular

  9. UNICELLULAR (algae) Euglenoids Flagella Diatoms Made of shells composed silica Dinoflagellates Cell spins b/c of two flagella MULTICELLULAR (seaweed) Green Alage Most diverse Red Algae Deep water Brown Algae air bladders help float—kelp Algae: Plant-Like Protists

  10. Algae: Plant-Like Protists euglena green algae diatoms red algae dinoflagelates brown algae

  11. Fungus-Like Protists • Absorb organic materials and nutrients • Resemble some types of fungi

  12. Protists and Disease • Giardiasis: causes severe diarrhea and intestinal cramps that can last for 2-6 weeks • Amebic Dysentery: causes pain, bloody diarrhea, and fever. Can be fatal if moves into brain • Toxoplasmosis: a small number of people develop flulike symptoms, dangerous to developing fetuses • Trichomoniasis: STD, women experience discolored discharge, genital itching, and urge to urinate. • Cryptosporidiosis: severe cramps and diarrhea that may last up to 2 weeks • Chagas Disease: spread by kissing bugs, and can cause several heart related issues • Malaria: spread by mosquitoes, causes liver damage and destroys red blood cells causing fever & Anemia. Can lead to death if left untreated.
