  1. CLASSIFICATION & 6 KINGDOM REVIEW NOTES

  2. Why do scientists classify organisms? • To organize the diversity of life 2. To help us know what we are talking about • Ex. Brown animal – beaver or bison?

  3. Classification Systems • In order to work well, a classification system must be established and logical • Furthermore, classification rules must have real biological meaning, so that you can identify an organism in the field • Don’t use (too broad): tall, colors, big, small • Do use (specific): greater than 2 meters in height, large eyes compared to head size, tail longer than body

  4. Classification Systems Cont. • We use the classification system developed by CarolusLinneaus. • His classification system consists of 7 levels; they are: • Kingdom, Phylum, Class, Order, Family, Genus, species

  5. Classification System • HintLevelsExampleBroadest • DaringDomain Eukarya • King Kingdom Animalia • Phillip Phylum Chordata • Came Class Mammalia • Over Order Carnivora • For Family Canidae • GreenGenus Canus • SpagettispeciesfamiliarisMost specific

  6. In this classification system, each organism has a two-part scientific name; this system of naming organisms is called binomial nomenclature • In particular, organisms must have a universally accepted name.

  7. We use Latin to name organisms, why? • 1. It is a dead, unchanging language • 2. There is no competition among countries

  8. Every scientific name has 3 parts: 1. The entire name is italicized or underlined. You NEED to UNDERLINE! 2. The name is made up of the Genus and species names of the organism 3. The first word is capitalizedand the second is lowercase. Examples: Homo sapiens, Canus familiaris, Equus caballus

  9. THE 6 KINGDOMS

  10. Archaebacteria • Domain: Archaea • Cell type: Prokaryotic • Structures: Ribosomes, cell wall • Unicellular • Ex: Methanogens & Halophiles

  11. Eubacteria • Domain: Bacteria • Cell type: Prokaryotic • Structures: Ribosomes, cell wall • Unicellular • Nutrition: Autotrophic or heterotrophic • Ex: Common bacteria (staph, strep)

  12. Protista • Domain: Eukarya • Cell type: Eukaryotic • Unicellular • Nutrition: Autotroph or Heterotroph • Ex: Ameba, Euglena, Paramecium

  13. Fungi • Eukaryotic • Nucleus, mitochondria, cell wall of chitin • Heterotroph • Mold, Yeast, Ringworm, Mushrooms

  14. Plantae • Eukaryotic • Multicellular • Autotrophic • Mosses, Ferns, Grass, Trees, Flowering plants

  15. Animalia • Eukaryotic • Nucleus, mitochondria, lysosome • Multicellular • Heterotrophic • Snakes, Worms, Dogs, Sponges, Insects, Humans
