  1. C17 Organizing Life’s Diversity

  2. A little history: • Aristotle (2000 years ago) • Plants and animals (2 kingdom system) • Carolus Linnaeus (1750s) • Binomial nomenclature • Genus species (Canis familaris, Canis lupus) http://www.stenudd.com/myth/greek/images/aristotle.jpg http://upload.wikimedia.org/wikipedia/commons/thumb/5/56/Carolus_Linnaeus_by_Hendrik_Hollander_1853.jpg/429px-Carolus_Linnaeus_by_Hendrik_Hollander_1853.jpg

  3. Taxonomy (define) • Domain contains Eukaryote • Kingdom contains Animalia • Phylum which contains Chordata • Class which contains Mammalia • Order which contains Carnivora • Family which contains Canidae • Genus which contains Canus • Species familaris http://www.findextrawork.co.uk/images/dog_nursery.jpg http://www.fw.delaware.gov/Info/DogControl.htm I can’t believe I’m going to say this, but see Wikipedia for examples

  4. How do they figure out what organism belongs in what group? Dichotomous Keys

  5. Taxonomy Cont. Phylogeny – theorized evolutionary history of a species Cladistics – closeness of organisms based on similarities of characteristics (organizing a closet) - classification based on phylogeny (also use of DNA & embryology & morphology) feathers fur, mammary glands Cladogram claws or nails lungs jaws http://www.cartage.org.lb/en/themes/Sciences/Zoology/Biologicaldiverstity/Classification/cladogram_1.gif

  7. 6 Kingdom System Archaebacteria Eubacteria Protista Fungi Plantae Animalia 5 Kingdom System Monera Protists Fungi Plantae Animalia 17.2 Intro to Kingdoms of LIfe 3 Domains: Archaea Bacteria Eukarya Interesting Fact: 99% of Animals are invertebrates 1% of Animals are vertebrates (fish, amphibs, reps, birds, mams

  8. Prokaryote vs Eukaryote • 2 kingdoms • No membrane bound organelle • Ribosomes • Circular chromosomes & plasmid • 1/10th the size of euks -4 kingdoms -Membrane bound organelle -Ribosomes -Linear chromosomes -10X the size of pros http://www.biologie.uni-hamburg.de/b-online/library/micro229/terry/images/other/pro_eu.GIF http://eesc.columbia.edu/courses/ees/slides/life/proeu.gif

  9. Get out Kingdom chart

  10. Organisms are put into Kingdoms based on: • Cell type • Cell construction • Body type • Unicellular vs Multicellular • Nutrition http://www.fas.org/irp/imint/docs/rst/Sect20/celltypes.jpg http://biology.unm.edu/ccouncil/Biology_124/Images/cellwall.jpeg

  11. Students gather general info from text on each kingdom

  12. Plants and Animal Kingdoms • Cells that differentiate • “division of labor” • Because cells differentiate can organize • Tissue • Organ • Organ sytem

  13. Pluipotent vs totipotent http://stemcells.nih.gov/StaticResources/info/scireport/images/figure42.jpg http://www.biology.arizona.edu/immunology/tutorials/immunology/graphics/cell.gif
