Ch. 14 & 19 notes Ch. 14 & 19 notes Presentation Transcript

  • Ch. 14 & 19 Notes
    “Classification and Intro. To Kingdoms”
  • A. Taxonomy-the science of naming and classifying organisms.
    B. Our system of classification was developed by Swedish biologist named Carl Linnaeus.
    C. He gave organism a specific name using binomial nomenclature-system of naming organisms using a 2 word name.
    1. The scientific name of an organism is made up of its genus and species name.
    Ex: humans-Homo sapiens
    Honeybee-Apismellifera
    I. Classification
  • 2. Rules for writing the scientific name:
    A. Capitalize the genus name.
    B. Underline or italicize both names
    C. Must be in Latin
  • D. Linnaeus grouped organisms into 7 categories based on similarities. Over time, these categories have been expanded to 8 categories:
    Domain
    Kingdom
    Phylum
    Class
    Order
    Family
    Genus
    Species

  • E. Classifying organisms can help determine the phylogeny, or evolutionary history of an organism.
  • A. All living things are placed into one of 3 domains.
    1. domain Bacteria-prokaryotes, thought to be the oldest.
    SpirilliaBacilliaCocci
    II. Introduction of the Kingdoms
  • 2. domain Archaea-prokaryotes, contain may extreme bacteria
  • 3. domain Eukarya-contains all four of the eukaryotic kingdoms.
  • B. All living things are placed into one of 6 kingdoms.
    1. Archaebacteria (domain Archaea) many live in extreme environments such as hot springs, salty lakes, volcanoes; all are prokaryotes.
  • 2. Eubacteria (domain Bacteria) all are prokaryotes.
  • 3. Protista (domain Eukaryo) all are eukaryotes,
    Eukaryotes that are not plants, animals, or fungi ex: amoeba, euglena, algae.
  • 4. Fungi (domain Eukaryo) all are eukaryotes and heterotrophic. Ex: yeasts, mushrooms, puffballs.
  • 5. Plant (domain Eukarya) all are eukaryotes and autotrophic. Ex: trees, grasses, ferns
  • 6. Animalia (domain Eukaryo) all are eukaryotes and heterotrophic. Ex: birds, fish insects
