2. The Classification System An Interactive PowerPoint Presentation by Stacey Podolsky

3. The Classification System Why do scientists classify? – –All living organisms have characteristics which distinguish them from nonliving objects – vi s so that organisms are easier to study –Scientists organize living things into groups so that organisms are easier to study

4. There Are Seven Levels of Classification 1.Kingdom 2.Phylum 3.Class 4.Order 5.Family 6.Genus 7.Species

5. The Five Kingdoms The Five Kingdoms The broadest level of organization Kingdoms Monera ArchaebacteriaEubacteria ProtistaFungiPlantaeAnimalia

6. Monera  Prokaryotes –Cells lack a nucleus –Absorbs its own food  Some form chains or mats  Bacteria, blue-green algae, and spirochetes –Over 10,000 known species

7. Monera Eubacteria and Archaebacteria –A growing number of researchers now divide this kingdom into 2 separate kingdoms Eubacteria –“The true bacteria” –Autotrophic and heterotrophic –Can cause: strep throat, used to produce yogurt, vitamins, etc. Archaebacteria –Autotrophic and heterotrophic –Live in: hot springs, on the ocean floor, salty water, your intestines

8. Video #1- Eubacteria E.coli Video contributed by Eric Knutsen

9. Protists Its members are very different from each other Its members are very different from each other –Can be autotrophic or heterotrophic –Most are unicellular  protozoa –some are multicellular  Seaweed Eukaryotic Eukaryotic –Its cells contain a nucleus To view video Click on Paramecium www.microscopy-uk.org.uk/mag/articles/param1.htmwww.microscopy-uk.org.uk/mag/articles/param1.htm. www.microscopy-uk.org.uk/mag/articles/param1.htm http://bio.rutgers.edu/~gb101/lab6_protists/r6a2paramec.ht ml http://bio.rutgers.edu/~gb101/lab6_protists/r6a2paramec.ht ml

10. Fungi Multicellular Eukaryotes Multicellular Eukaryotes Mushrooms Mold Mildew Unicellular Eukaryotes Unicellular Eukaryotes yeast

11. Plantae  Multicellular eukaryotes  Autotrophs Photosynthetic  They make their own food Mosses, ferns, woody and non-woody flowering plants

12. Animalia All are multicellular eukaryotes Heterotrophs They have their own means of locomotion

13. Dog Classification  Kingdom –Animalia  Phylum –Groups of classes  Chordata  Class –Groups of orders  Mammalia  Order –Groups of families  Carnivora

14. Dog Classification cont.  Family –Groups of species  Canidae  Genus –Groups of closely related species  Canis  Species –Groups of related organisms  Familiaris

20. There are 7 levels of Classification CORRECT! Back

21. CORRECT! Kingdom is the broadest level of organization. Back

22. CORRECT! Mushrooms, Mold and Mildew are examples of multicellular organisms. Back

23. CORRECT! All organisms in the ANIMALIA kingdom are multicellular eukaryotic organisms. Back www.justgive.org/Images/ways/sugarbear.jpg

24. CORRECT! Eubacteria and Archaebacteria A growing number of researchers now divide the MONERA kingdom into 2 separate kingdoms Back
