  1. Name the eight levels of classification.
    • Domain
    • Kingdom
    • Phylum (Division in plants)
    • Class
    • Order
    • Family
    • Genus
    • Species

    ( Did King Phillip Come Over For Grape Soda?)
  2. taxonomy
    the science of giving unique and meaningful names to all the species on Earth
  3. Carolus Linnaeus
    in the mid 1700's developed classification system Systema Naturae
  4. systematics
    the science of identifying relationships among species
  5. Name the three DOMAINS
    • Bacteria
    • Archaea
    • Eukarya
  6. main characteristics of Domain Bacteria
    • unicellular prokaryoates (lack nucleus)
    • heterotrophic (must eat to obtain energy)
  7. cyanbacteria
    • exception: autotrophic (can convert energy)
    • use photosynthesis
  8. main characteristics of Domain Archaea
    • unicellular prokaryoates
    • extremophiles
  9. Name the four Kingdoms in Domain Eukarya
    • Protista
    • Plantae
    • Animalia
    • Fungi
  10. main characteristics of Kingdom Protista
    • diverse group of microorganisms
    • unicellular eukaryotic (have nucleus)
    • all organisms not in other three kingdoms
    • may be autotrophic or heterotrophic
  11. main characteristics of Kingdom Plantae
    • most multicellular
    • have cell walls made of celluose
    • typically non-motile
    • autotrophic (convert enery through photosysthesis)
  12. main characteristics of Kingdom Animalia
    • most multicellular
    • lack cell walls
    • many are capable of movement or movement of body parts, at some time
    • heterotrophic (eat to obtain energy)
  13. main characteristics of Kingdom Fungi
    • multicellular
    • typically non moving
    • cell wall containing chitin (not cellulose)
    • heterotrophic
    • many are decomposers (obtain energy by breaking down dead, decaying organisms)
  14. Rules fror naming species
    • 1. binomial: genus and species epithet
    • 2. unique
    • 3. Latinized
  15. common practices when naming species
    • 1. Name after region where found
    • 2. Name after person
    • 3. Describe a characteristic
  16. rules for writing scientific name
    • Genus is capitalized, species is not
    • italicized if typed
    • underlined if hand written
  17. phylogeny
    the evolutionary relationshipd among species ; can be represented by a pattern of ancetry and descent
  18. speciation
    the process of evolution of more than one (usually two) new species from a pre-existing species
  19. phylogenetic tree
    depicts pattern of ancestry and descent amoung species

    • tips: extant species
    • branches: relationships among species
    • nodes: where braches meet, common ancestor
    • root: oldest shared ancestor
    • outgroup: rest of the scies
    • polytomy: multiple branches in one node
  20. clades
    a specific group that includes a common ancestor and all its descendants
  21. shared derived characters
    character shared by all members of a clade indentifed by a mark on the branch of tree and desciption
  22. diagnostic characters
    unique character used to identify species using a key
