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. http :// www.cartage.org.lb/en/themes/Sciences/Zoology/Biologicaldiverstity/Classification/cladogram_1.gif 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) fur, mammary glands claws or nails lungs jaws feathers Cladogram

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

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