  1. taxonomy How we classify organisms based upon structural similarities and differences

  2. Carolus Linnaeus • The “Father of Modern Taxonomy” • Established methods for classifying and naming organisms that are still used • BINOMIAL NOMENCLATURE • Two name names

  3. Five kingdoms system • The most general classification • Monera – bacteria • Protist • Fungi • Plants • animals

  4. Kingdom Monera • Prokaryotic • No membrane-bound organelles • No nuclear membrane • Unicellular • Some are heterotrophic • cyanobacteria are autotrophic because they perform photosynthesis

  5. Protists • Eukaryotic • Membrane-bound organelles • Nuclear membrane • Mainly unicellular • Some are heterotrophic and some are autotrophic

  6. protozoa • These do not have cell walls • Examples include ameba and paramecium

  7. Algae • These protists have cell walls and chloroplasts • These protists are autotrophic • Some are multi-cellular like sea weed!

  8. Blue algae

  9. fungi • Fungi are eukaryotic • Fungi can be unicellular • Yeast and bread mold • Fungi can be multicellular • mushrooms • All fungi are heterotrophic

  10. A fungus lives on its food source • They absorb the nutrients they need from the environment • Digestive enzymes are secreted into their food source for EXTRACELLULAR digestion • The end products of digestion (nutrients) are absorbed

  11. Plants • All plants are multicellular • All plants are eukaryotic • All plants are autotrophic • Plant cell walls are made of cellulose

  12. bryophytes • No true roots stems or leaves • No vascular tissue to circulate food or water • They are only a few centimeters in height • Must live in a moist area • mosses

  13. Tracheophytes • True roots, stems and leaves • They have vascular tissue to circulate food and water • They can grow to great heights • They can live in many different environments

  14. Animals • All animals are eukaryotic • All animals are multicellular • All animals are heterotrophic

  15. Classification Kingdom – most general Phylum – related classes Class – related orders Order – related families Family – related genus Genus – related species Species – most specific

  16. Species name • Based on a system of binomial nomenclature • The Latin version of the genus and species of an organism • Members of a species must be able to successfully reproduce and have fertile offspring

  17. Human Animalia Chordata Mammalia Primates Hominid Homo Homo sapien Chimpanzee Animalia Chordata Mammalia Primates Pongid Pan Pan troglodyte Human versus chimpanzee
