Transcript

  • 1. 12 The Eukaryotes: Fungi, Algae, Protozoa, and Helminths
  • 2. The Protozoa Table 12.1
  • 3. Protozoa
    • Eukaryotic
    • Unicellular
    • Chemoheterotrophs
    • Vegetative form is a trophozoite.
    • Asexual reproduction is by fission, budding, or schizogony.
    • Sexual reproduction by conjugation.
    • Some produce cysts.
    Figure 12.16
  • 4. Archaezoa
    • No mitochondria
    • Multiple flagella
    • Giardia lamblia
    • Trichomonas vaginalis (no cyst stage)
    Figure 12.17b–d
  • 5. Microspora
    • No mitochondria
    • Nonmotile
    • Intracellular parasites
    • Nosema
  • 6. Amoebozoa
    • Move by pseudopods
    • Entamoeba
    • Acanthamoeba
    Figure 12.18a
  • 7. Apicomplexa
    • Nonmotile
    • Intracellular parasites
    • Complex life cycles
    • Plasmodium
    • Babesia
    • Cryptosporidium
    • Cyclospora
  • 8. Plasmodium 2 3 6 7 8 Figure 12.19
  • 9. Cryptosporidium Figure 25.19
  • 10. Ciliophora (Ciliates)
    • Move by cilia
    • Complex cells
    • Balantidium coli is the only human parasite.
    Figure 12.20
  • 11. Euglenozoa
    • Move by flagella
    • Photoautotrophs
      • Euglenoids
    • Chemoheterotrophs
      • Naegleria : Flagellated and amoeboid forms; causes meningoencephalitis.
      • Trypanosoma : Undulating membrane, transmitted by vectors.
      • Leishmania : Flagellated form in sand fly vector, ovoid form in vertebrate host.
  • 12. Euglenozoa Figure 12.21
  • 13. Dinoflagellates
    • Why are these studied with algae and protozoa?
    Figure 12.14
  • 14.
    • Cellular slime molds
      • Resemble amoebas, ingest bacteria by phagocytosis.
      • Cells aggregate into stalked fruiting body.
      • Some cells become spores.
    • Plasmodial slime molds
      • Multinucleated large cells.
      • Cytoplasm separates into stalked sporangia.
      • Nuclei undergo meiosis and form uninucleate haploid spores.
    Slime Molds
  • 15. Cellular Slime Mold Figure 12.22
  • 16. Plasmodial Slime Mold Figure 12.23 (1 of 2)
  • 17. Slime Molds
    • Why are slime molds included with the Amoebozoa?
    Figure 12.23 (2 of 2)
