  1. ClassificationChapter 45-Kingdom System

  2. Taxonomy – the science of classifying organisms by their similarities in traits.

  3. Carolus Linnaeus • 1758 – came up with a system of classification based on 2 kingdoms: • Animal kingdom • Plant kingdom • What discovery changed this?

  4. Discovery of Euglena

  5. System of Classification Domain Dumb Kingdom Kids Phylum Playing Class Chicken Order On Family Freeways Genus Get Species Smushed

  6. Naming Organisms • Use the genus and the species name for the scientific name – binomial nomenclature (2 name naming). • Humans = Homo sapiens • Blue whale = Balaenoptera musculus • Great white shark = Carcharodon carcharias

  7. The Five Kingdoms

  8. Kingdom Monera • AKA - bacteria • Single-celled • Prokaryotic • Autotrophic or Heterotrophic • Cell wall • Asexual reproduction • May be able to move

  9. Kingdom Monera

  10. Kingdom Protista • Eukaryotic • Single or multicellular (mostly single) • Autotrophic or heterotrophic • The protist kingdom is like a grab bag or junk drawer. • Includes amoeba, euglena, paramecium, algae, seaweed, etc.

  11. Kingdom Protista

  12. Kingdom Fungi • Eukaryotic • Single-celled (yeasts). Most are multicellular (mushrooms on pizza) • Saprophytic (heterotrophs that absorb nutrients from dead or dying tissue) • Sexual or asexual reproduction • No fungi in the oceans – can’t take the salt

  13. Kingdom Fungi

  14. Kingdom Plantae • Eukaryotic • Multicellular • Autotrophic • Cell wall • Sexual or asexual reproduction

  15. Kingdom Plantae

  16. Kingdom Animalia • Eukaryotic • Multicellular • Heterotrophic • No cell wall • Usually reproduce sexually

  17. Kingdom Animalia

  18. 5 Kingdoms have become 3 Domains and 4 Kingdoms

  19. Kingdom Monera has been split Domain Eubacteria Domain Archaebacteria

  20. Domain Archaebacteria • “Architects of the Atmosphere” • Earliest life forms with fossil 3.5 billion years old • Autotrophic • Extreme acidophiles, halophiles, and methanogens.

  21. Domain Eubacteria Includes all the bacteria that are not archaebacteria. Not photosynthetic – decomposers and disease-causing

  22. Domain Eukarya • Includes the other 4 kingdoms • Protista • Fungi • Plantae • Animalia

  23. What will be the next change(s)? • Will protists be moved into the other kingdoms? • Will viruses be considered alive and moved into their own kingdom or domain?
