  7. Kingdom, Phylum, Class, Order, Family, Genus, Species • Taxonomy classified living organisms by their physical characteristics. That was all the scientists of the time could see. • Linneusdivided living things into 2 kingdoms: PLANTS AND ANIMALS • After the invention of the microscope, it was quickly determined that the physical characteristics we could see were not enough to classify some organisms. Scientists had to consider cellular differences and molecular differences….. So

  8. Our classification of living things has expanded to include cellular and molecular level differences observed in the microscope and the laboratory. • There are now 3 Domains and 6 Kingdoms! SO WHAT ARE THE CURRENT DOMAIN AND KINGDOMS? Some look familiar; a few look new. Those darn bacteria really did not fit in with plants or animals and had to have their own domain!

  9. Domain Kingdom Examples Bacteria Eubacteria Streptocuccus, E. coli ArchaeaArchaebacteria Methanogens, halophiles EukaryaProtist Amoeba, Paramecium slime molds Fungi Mushrooms, yeasts Plantae Mosses, ferns, flowering plants Animalia Sponges, insects, worms fishes, mammals

  10. So the Domain is the most inclusive (least specific category), • Domain • Kingdom • Phylum • Class • Order • Family • Genus • Species

  11. So what do modern day scientists look at to group organisms into particular categories? • LOOKING AT EXAMPLE

  12. Here is an interesting thought Science has come a long way even from the species category to very specifically identify living things. We are all humans, but other than physical characteristics; hair color, height, etc. humans are identified by Fingerprints! AND even more specific ???? Our molecular structure instructions DNA

  13. Pick up a book from the room copy shelves and begin WS 18-3. Read then answer questions. Any you do not finish in class is HW • Read the Cytology Lab to become familiar with the procedure. Lab starts on Tuesday. • Your other HW assignment is Extra Credit Flashcards of the Unit 3 Vocab. We have 1 section left, then it will be test time on Unit 3. • Unit 3 test date = Monday November 12
