1. Classification Diversity of Living Organisms

2. How Classification Has Changed  Taxonomy  Began with Linneaus (1700s)  Used primarily physical characteristics  Cladistics  Shows evolutionary relationships  Evidence includes: geographic distribution, DNA evidence, fossil record

3. How taxonomy works  Did King Philip Come over for Good Soup?  Which taxon is more inclusive?  Which taxon is least inclusive?

4. Provides a naming system  Binominal nomenlature :  Genus species or Genus species

5. Think…Pair…Share Time  Which taxon contains greater diversity? Order or Family? Explain.  Who is more closely related? Explain.  Ursus americanas and Ursus arctos  Ursus arctos or Lepitus arctos

6. What is the “Did”?  Domain : A taxon that was added that is more inclusive than Kingdom.  Separates bacteria into two kingdoms groups and places everything else in one large group:  Archaea  Bacteria  Eukarya

7. Challenge!  Archae means “ancient”. Is this a good name for Archaebacteria? As you research the 3 domains and six kingdoms you will gather evidence to explain why or why not!

8. 6 Kingdom Model: Let’s fill in the top of our graphic organizer!

9. Group Challenge  Using the various biology books provided in the classroom, you will fill in the graphic organizer to show the key characteristics of one kingdom. Then we will share!!!  The next set of slides explain what each of the characteristics you will find are.

10. Pages in Campbell’s (Green)  Tables 271 & 27.2 (533 & 537)  522-523 (6 Kingdom Model)  535-537 (Archaea vs. Bacteria)  545-548 (Protists)  582-584 (Plants)  616-619 (Fungi)  633-634 (Animals)

11. Energy Use  Organisms must obtain energy…  How do they get their energy?  Autotroph…most use sunlight “photo”  Heterotroph:  Ingestion  Decomposition  How do they use their energy (respiration)?  Aerobic  Anaerobic

12. Organization of Genetic Material  Nucleus and Organelles  Eukaryotic  Membrane bound organelles  Prokaryotic  Organization of DNA within the nucleus  Introns: Non-coding regions of DNA (used to be called “junk”  Histones: Proteins which DNA is wrapped around!

13. Organization at the cellular level  # of Cells:  Unicellular  Colonial  Multicellular  Cell Wall  Do all members have a cell wall?  What material is the cell wall made of?

14. Reproduction and Motility  Life Cycle  Are the organisms primarily sexual or asexual?  Are there any special details about their life cycle?  Motility  Do the organisms have structures specialized for movement?

16. After we share…  What other things seem to group your organisms?

17. Think…Pair…Share challenge  Protista problem!  The protista kingdom is problematic. It doesn’t fit the model well. What problems are there with the current structure of the protista kingdom?

18. How might this model solve the protista problem?

19. Pair Challenge!  Use your graphic organizers to determine which kingdom each organism in the kingdom scavenger hunt belongs to!  As you are doing that, keep in mind which characteristics help define a kingdom!

20. Individual Challenge:  Highlight which characteristics are most important to identifying each kingdom.  Do you have to “memorize” the kingdom graphic organizer?

21. Assessment  Microbe Zoo Project  Critical Thinking: What characteristics lead to the classification of specimens? Identify why each of you model microbes is a good example of a Domain and/or Kingdom OR why a microbe does not fit.  Product: Can you display your information in a way that both casual and formal learning can take place can …can you make it interactive?!?
