  1. 1. Changing Number of KingdomsChapter 17.3- Domains and Kingdoms
  2. 2. Kingdoms and Domains: Scientists debate how many kingdoms there are.The three-domain system Bacteria Archaea EukaryaThe six-kingdom system Bacteria Archaea Protista Plantae Fungi AnimaliaThe traditional five-kingdom system Monera Protista Plantae Fungi Animalia BioEd Online
  3. 3. Domains There are 3 Domains Bacteria- cells contain cell walls with Peptidoglycan (polymer that has 2 kings of sugar). Archaea- cells contain cell walls without Peptidoglycan. Eukarya- contains Eukaryotic cells. Contains the Kingdoms Protista, Fungi, Plantae and Animalia
  4. 4. Kingdom Bacteria• Unicellular and prokaryotic
  5. 5. Kingdom Archaea• Unicellular and Prokaryotic• Live in some of the most extreme environments you can imagine
  6. 6. Kingdom ProtistaEukaryotic organisms that can beunicellular or multicellular. Has no organs.Ex: plant like protist = algaeEx: animal like protist = protozoansEx: fungus like protist = molds & mildews
  7. 7. Kingdom FungiUnicellular or Multicellular Eukaryotes thatabsorbs nutrients (heterotrophs).Contains chitinEx: Mushrooms
  8. 8. Kingdom PlantaeMulticellular Eukaryotes that are autotrophs.Contains cellulose
  9. 9. Kingdom AnimaliaMulticellular Eukaryotes that areheterotrophs. Has no cell wall.
