1. Warm-up! 2/1 What is the name of the man who developed our current system of classification and what are the 7 levels of his system?

2. The 6 Kingdoms of Life

3. Important Terms!  Prokaryote – A simple cell with NO nucleus and no organelles. Always unicellular. These were the very first cells!  Eukaryote – A complex cell with a nucleus and organelles. Can be uni or multi-cellular.

4. Important Terms!  Autotroph – ‘Self feeder.’ Can make its own food from sunlight or chemicals.  Heterotroph – ‘Other feeder.’ Must consume other organisms for food.

5. Important Terms!  Unicellular – the organism is made of only 1 cell.  Multicellular – the organism is made of more than 1 cell.

7. Animalia  All multi-cellular  Cells are Eukaryotic contain a nucleus and membrane bound organelles  Cells lack cell walls  Heterotrophs (cannot make their own food)  Cells are specialized for particular functions

9. Plantae   All plants are multi-cellular Eukaryotes   Contain chlorophyll for capturing sunlight!   Are autotrophs! Make their own food!   All plants reproduce sexually

10. Mold Yeast Ringworm Mushrooms

11. Fungi  Do not contain chlorophyll (non- photosynthetic)  Important decomposers  Most are multi-cellular eukaryotes, but some are unicellular like yeast  Cell walls are made of chitin (a complex sugar)

12. Warm-up! 2/1 In the forest I find a multi cellular eukaryotic organism with cell walls made of chitin – to which of the 6 Kingdoms does it belong?

14. Archaebacteria  Found in harsh environments (undersea volcanic vents, acidic hot springs, salty water)  Cell walls without peptidoglycan  Subdivided into 3 groups based on their habitat --- methanogens, thermoacidophiles, & extreme halophiles  Some of the oldest living things!!!

15. Thermophiles (like heat) Halophiles (like salt/sulfur)

16. Eubacteria Most are heterotrophic (can’t make their own food)  Cell walls made of peptidoglycan  Prokaryotic!  Can be identified by Gram staining (gram positive or gram negative)  Can be identified by Gram staining (gram positive or gram negative)

17. Eubacteria  Staphylococcus aureus  Staphylococcus aureus  Treponema pallidumcholera (syphilis)  Escherichia coli

18. Protist  Eukaryotes  Most are unicellular  Heterotrophs that ingest small food particles & digest it inside food vacuoles containing digestive enzymes  Classified by the way they move (cilia, flagella, pseudopodia...)

19. Amoeba Euglena Rotifer Algae Volvox Spyrgyra

20. Ticket – Kingdoms Take out a sheet of paper and tear it in half. Share with a neighbor. You may use the notes you just took. Are you ready?

21. Warm-up! 2/2 1. I find a creature with no cell walls – to what kingdom does it belong? 2. I find an organism with eukaryotic cells – it could belong to any of which 4 kingdoms?

24. 1. Which Kingdom do I belong to?

25. 2. Which Kingdom do I belong to?

26. 3. Which Kingdom do I belong to?

27. 4. Which Kingdom do I belong to?

28. 5. Which Kingdom do I belong to?

29. 6. Which Kingdom do I belong to?

30. 7. Which Kingdom do I belong to?

31. 8. Which Kingdom do I belong to?

32. 9. Which Kingdom do I belong to?

33. 10. Which Kingdom do I belong to?

34. Warm-up! 2/3 A bacteria is growing in an acidic pool of water. Its cell walls are made without peptidoglycan. What Kingdom does it belong to?

35. Warm-up! 2/3 A bacteria is growing in a salty pool of water. It’s cell walls are made without peptidoglycan. What Kingdom does it belong to? Archeabacteria

39. Important Classes from Kingdom Animalia! There are LOTS of classes in the animal kingdom – we are going to talk about 6: Insecta Osteichthyes (bony fishes) AmphibiaReptilia Aves (birds) Mammalia (us!)

40. Linnaeus’s Hierarchy of Classification  Kingdom  Phylum  Class  Order  Family  Genus  Species The system is a hierarchy, that is consists of levels. Kingdom is the largest level and species is the smallest level.

41. Linnaeus’s Hierarchy of Classification  KingdomAnimalia  PhylumChordata  ClassMammalia  Order Primates  FamilyHominidae  GenusHomo  SpeciesSapien

42. Linnaeus’s Hierarchy of Classification  KingdomAnimaliaAnimalia  PhylumChordataChordata  ClassMammaliaReptilia  Order PrimatesSquamata  FamilyHominidae Veranidae  GenusHomoVeranus  SpeciesSapien Komodoensis

43. Important Animalia Terms!  Vertebrate – an animal that has a backbone  Invertebrate – an animal without a backbone

44. Important Animalia Terms!  Endotherm – a warm blooded animal (makes its own body heat)  Exotherm – a cold blooded animal (must absorb heat from its surroundings)

46. Important Classes from Kingdom Animalia! Which class is made of invertebrates? Insecta Osteichthyes (bony fishes) AmphibiaReptilia Aves (birds) Mammalia (us!)

47. Important Classes from Kingdom Animalia! Which classes are warm-blooded? Insecta Osteichthyes (bony fishes) AmphibiaReptilia Aves (birds) Mammalia (us!)
