  1. Kingdoms and Domains

  2. QCC • 13.3 Describes characteristics of organisms and identifies examples of at least five different kingdoms. • 13.4 Identifies common examples of organisms in each of the kingdoms.

  3. Recall Taxonomic Levels • Kingdom • Phylum • Class • Order • Family • Genus • Species

  4. Levels Greater Than Kingdoms • These are called domains • Remember two different types of cells • Prokaryotes • No nucleus • No organelles • Eukaryotes • Contain nucleus • Have organelles • Plant vs. Animal

  5. Domains • Three Domains • Bacteria • Archaea • Eukarya

  6. Domain Bacteria • Unicellular and prokaryotic • Have thick, rigid cell walls • Corresponds to the kingdom Eubacteria • Contain free-living soil organisms to deadly parasites • Some photosynthesize • Some need oxygen to survive, while others are killed by oxygen

  7. Domain Archaea • Also unicellular and prokaryotic • Live in volcanic hot springs, brine pools, and black organic mud totally devoid of oxygen (some of the most extreme environments) • Many can survive only in the absence of oxygen • Cell walls lack peptidoglycan • Corresponds to the kingdom Archaebacteria

  8. Domain Eukarya • Consists of all organisms that have a nucleus (Eukaryotic) • Organized into the four remaining kingdoms • Protista • Fungi • Plantae • Animalia

  9. Six Kingdoms • Eubacteria • Archaebacteria • Protista • Fungi • Plantae • Animalia

  10. Kingdom Protista • Composed of eukaryotic organisms that cannot be classified as animals, plants, or fungi • Members display the greatest variety

  11. Kingdom Fungi • Heterotrophs • Most feed on dead or decaying organic matter • These fungi secrete digestive enzymes into their food source then absorb the smaller food molecules into their bodies

  12. Kingdom Plantae • Multicellular organisms that are photosynthetic autotrophs • Plants are nonmotile • Cell walls that contain cellulose

  13. Kingdom Animalia • Multicellular and heterotrophic • Do not have cell walls • Most animals can move about, at least for some part of their life cycle
