  1. CHAPTER 17 QUIZ • You have 20 minutes to complete the quiz. • DO YOUR OWN WORK. • Pick up a Chapter 18 Reading Packet after you have handed in your quiz. • Packets on front table.

  2. NOVA – The First Primates • http://www.youtube.com/watch?v=W_X5ciqtbG0

  3. AGENDA April 1 • Big Question: How are different organisms classified? • QUIZ • 1. Question of the Day and DO NOW • 2. 18-1 Order in Diversity • 3. 18-1 Guided Reading Questions • 4. Review and Homework • STUDY YOUR NOTES!!!

  4. Question of the Day Apr 1 • Simply by reading its name, you know that the organism Rhizopusnigricansis • A. a plant • B. an animal • C. in the Genus Rhizopus • D. in the Genus nigricans

  5. DO NOW Apr 2 • Develop a system to classify teachers at PTHS. • You must have at least 5 different identifiers (factors) to classify teachers.

  6. DO NOW ANSWERED Apr 2 • Share your answers. • 3 Volunteers write your factors on the boards. • Are they logical systems of identification?

  7. AGENDA April 2 • Big Question: How are different organisms classified? • 1. Question of the Day and DO NOW • 2. 18-1 Order in Diversity • 3. 18-1 Guided Reading Questions • 4. Review and Homework • STUDY YOUR NOTES!!!

  8. Chapter 18: Classification

  9. 18-1: Order in Diversity • Huge diversity of life • Must be a way to classify them • Taxonomy – scientific classification of organisms with universally accepted names. • What is the name of this animal? • Cougar, panther, mountain lion, puma •  All are acceptable.

  10. Scientific Names • Puma concolor • Binomial Nomenclature • Developed by Carolus Linnaeus • Two-part scientific name • Names are Italicized • First letter-first word capitalized • Second word is lower-case • Ursusmaritimus • (GENUS) species name

  11. Linnaeus’s System of Classification • King KINGDOM • Philip PHYLUM • Came CLASS • Over ORDER • From FAMILY • Great GENUS • Spain SPECIES

  12. DO NOW Apr 3 • Develop a system to classify teachers at PTHS. • You must have at least 5 different identifiers (factors) to classify teachers.

  13. DO NOW – Possible ANSWER • 1. Department – Science, History, Math • 2. Subject Taught – Biology, Physics, Chemistry • 3. Classroom – 417, 410, 407 • 4. Gender of Teacher – Male or Female • 5. Physical Traits - Hairstyle

  14. AGENDA April 3 • Big Question: How are different organisms classified? • 1. Question of the Day and DO NOW • 2. 18-2/18-3 • 3. Chapter 18 HW Check • 4. Review and Homework • STUDY YOUR NOTES!!!

  15. 18-2 Modern Evo Classification • Linnaeus grouped species visible similarities and differences. • Evolutionary classification based upon evo history. • Phylogeny – grouping of organisms through lines of evolutionary descent. • Descent with modification • may physically appear similar • very different morphologically and physiologically.

  16. Cladograms • Derived characteristics appear in recent parts of lineage. • Used to construct cladograms. • Show evolutionary relationships Mini-LAB Page 453 Draw a cladogram Hint: Begin with a trait that only one organism is missing

  17. Shared Common Traits • DNA and RNA • Genes  Human and yeast genes both code for MYOSIN • DNA Evidence  Very different looking organisms have similar mechanisms • American vulture closer to Stork than African vulture • Molecular clocks uses DNA comparisons to estimate time that two species have evolved independently.

  18. Question of the DAY Apr 4 • In phylogeny, what is the name given to a group of organisms and all of its common ancestors and descendants? • A. Cladogram • B. Clade • C. Food web • D. Energy pyramid

  19. Question of the Day • A clade is a grouping that includes a common ancestor and all the descendants (living and extinct) of that ancestor. • Imagine clipping a single branch off the phylogeny — all of the organisms on that pruned branch make up a clade.

  20. AGENDA April 4 • Big Question: How are different organisms classified? • 1. Finish Chapter 18 • 2. Study Guides • Chapter 17/18 Test on MONDAY April 7 • 3. Review and Homework • STUDY for TEST.

  21. 18-3 Kingdoms and Domains • Five Kingdoms  SIX Kingdoms • Eubacteria, Archaebacteria, Protista, • Fungi, Plantae, Animalia • THREE-Domain System • 1. Eukarya • 2. Bacteria • 3. Archaea

  22. Three Domains • 1. BACTERIA • Unicellular and prokaryotic • Cell walls contain peptidoglycan • Very diverse survival mechanisms • 2. ARCHAEA • Unicellular and prokaryotic bacteria • Extreme environments, most are anaerobic • Unique lipids in cell walls • 3. EUKARYA • Eukaryotic • Kingdom Protista, Fungi, Plantae, and Animalia

  23. Domain Eukarya • PROTISTA • Eukaryotic • Not classified as animals, plants, or fungi • characteristics of all three displayed • Members have greatest variety • Most unicellular • Photosynthetic or Heterotrophic

  24. Domain Eukarya • FUNGI • Heterotrophs • Feed on dead/decaying matter • Secret digestive enzymes • Absorb smaller food molecules • Multicellular – Mushrooms • Unicellular - Yeast

  25. Domain Eukarya • PLANTAE • Multicellular • Photosynthetic • Nonmotile • Cell walls contain cellulose • Cone-bearing and Flowering • Mosses and ferns

  26. Domain Eukarya • ANIMALIA • Multicellular • Heterotrophic • No cell walls • Have motility
