  1. Hand in Using the Microscope and W.S. “Parts of Eukaryotic Cells” before the bell rings. 4B Only hand in Using the Microscope if you’re finished Test Review Chapter 3 Review Sheet Topics Notes – Chapter 4 "Learning is not attained by chance, it must be sought for with ardor and attented to with diligence." Abigail Adams, 1780 (in a letter to son, John Quincy Adams) To learn about cells and their organelles Title: Biology 10/31/06 Class Topics Objectives: Friday, December 20, 20194:11 AM

  2. Class Assignments What By When • Lab – Using the microscope 10/31/06 • W.S. “Parts of the Eukaryotic Cell” 10/31/06 • W.S. “Chapter 3 Review Sheet” 10/31/06 • 4B only “Chapter 3 Review Sheet” 11/2/06 • Chapter 3 Test 11/2/06 • All Chapter 3 corrections 11/6/06 • Due this class period • Due next class period • Due in the future

  3. Grade Sheet 1A – SR p. 61 - 5 pts Measurement W.S. – 10 pts 3A SR p. 42 – 6 pts 4A – SR p. 47 – 5 pts 2A – Measurement W.S. – 10 pts

  4. Chapter 3 Review Sheet • Work together to complete the review sheet • Turn in as you complete it • Correct homework or review for test next class period

  5. Protein Production • 1. Nucleus • DNA forms mRNA • 2. Ribosomes (RER) • mRNA is used to form protein • 3. vesicle from RER to Golgi • 4. Golgi • Packaged for shipping • 5. vesicle to cell membrane for release

  6. Chapter 3 Test Review • Hooke • Magnification • Eyepiece x objective • Light microscope • 2000x • resolution • Scanning tunneling • Cell Theory • All cells have…

  7. Chapter 3 Test Review • Surface Area:Volume • Small cells better (why?) • Volume up, Surface area? • Cell size up, ratio? • Cell membrane • Proteins (4) • Short answer • Lipid bilayer • Phospholipid • Purpose (selectively permeable)

  8. Chapter 3 Test Review • Prokaryotic vs Eukaryotic • Nucleus, MBO, examples • Label • Golgi, • Mitochondrion • ribosomes • RER • Releases vesicles • Location of DNA

  9. Chapter 3 Test Review • Organelles • Definition • Vesicles w/protein • ATP Production • Golgi • Ribosomes • Chloroplast • Vacuole • Mitochondria • Similarity with chloroplast, too • RER

  10. Chapter 3 Test Review

  11. Chapter 3 Test Review • Nucleus • Parts • Plant/animal • Essays • Endosymbiont hypothesis • What is the hypothesis? • What organelles fit the hypothesis? • Evidence for the hypothesis • Cell as a factory analogy • Choose 6 organelles and explain how each would serve as a factory part

  12. Passive Transport • The movement of molecules through a membrane without any energy from the cell. • DIFFUSION • Molecules will move from areas of high concentration to areas of low concentration • Equilibrium – Concentration is equal throughout a space. • End of diffusion
