  1. Life, as we call it.

  2. Life, as we call it. I suppose that before we talk about life, we should somehow name it….

  3. Classifying Organisms • You have at least a two part name…..your first, and your last. • For example, George Washington. • First name George, last name Washington. • …..Duh!

  4. Classifying Organisms • Scientist also give two part names to organisms. This two part name is called…. • Binomial Nomenclature. • A two part naming system.

  5. Classifying Organisms. • In the case of George Washington, the name describes a person named George of the family Washington. • In the cases naming organisms, it’s similar but a little different.

  6. Classifying Organisms. • Let’s use the common house cat as an example… • Felis domesticus. • The first part of the name is called…. • Genus • First name (always capital case) • refers to similar closely related organisms

  7. Classifying Organisms. • Continuing Felis domesticus • The second name is the……. • Species • A group of organisms that can mate and produce fertile offspring in nature. • Lower case

  8. Classifying Organisms. • So, in the case of Felis domesticus (the common house cat) Felis is the genus and domesticus is the species. • You can tell the house cat is related to the puma because the puma’s scientific name is Felis concolor. • Both from the same genus.

  9. Classifying Organisms. • As it turns out, there is more than just a genus and species involved in naming organisms. In fact there are 7 steps or levels in classifying organisms.

  10. The seven levels of classification. • 1 - Kingdom Kings • 2 - Phylum Play • 3 - Class Cards • 4 - Order On • 5 - Family Fat • 6 - Genus Green • 7 - Species Stools

  11. The seven levels of classification. • How ‘bout a human • Kingdom - Animalia • Phylum - Chordata • Class - Vertebrata • Order - Mammalia • Family - Primates • Genus - Homo • Species - sapiens

  12. The seven levels of classification. • How can this easily be applied to identify an organism? • Scientist and others will frequently use a… • Taxonomic Key • A series of paired statements that describe physical characteristics.

  13. The seven levels of classification. • Taxonomic Key Example Web site

  14. The Kingdoms • There are a total of 6 Kingdoms for all life based on their cell type, ability to make food and cell number.

  15. The Kingdoms • 1. Archaebacteria. • 2. Eubacteria. • 3. Protist. • 4. Fungi. • 5. Plants. • 6. Animals.

  16. The Kingdoms • 1. Archaebacteria • “Ancient Bacteria” • Unicellular Prokaryote • Found in boiling hot vents….and you. • autotrophs and heterotrophs

  18. The Kingdoms • 2. Eubacteria • Unicellular Prokaryote • Different cell chemistry from Archaebacteria • autotrophs and heterotrophs

  21. The Kingdoms • 3. Protist • Mostly unicellular eukaryote • Seaweeds and other colony organisms are exceptions • autotrophs and heterotrophs

  24. The Kingdoms • 4. Fungi • Mostly multicellular eukaryotes • All are heterotrophs • Mushrooms, molds and mildew….yuck

  29. The Kingdoms • 5. Plants • All multicellular eukaryotes • Autotrophs …Yes I know, what about venus fly traps and such

  30. The Kingdoms • There are about 9 Phylums (divisions) of plants. Moss, whiskferns, horsetails, ferns, cyads, maidenhair trees, pine trees, roses, and gnetophytes, which are cone-bearing desert plants.

  31. Bryophyta Moss http://www-biol.paisley.ac.uk/bioref/Bryophyta/Polytrichum_commune.html

  32. Phylum: Psilotophyta http://www.washjeff.edu/greenhouse/Pnudum/
