TOPIC: Cells Wed 11.28.12 MY GOAL: I will pass MiniSum #2 on Cells & finish the Cell Lab Get On Task 1. Review for MiniSum Types of scopes ISN p.86 Light Stereo/ LightMicroscope Stereo/ Dissecting Microscope Dissecting Microscopee Microscop Microscope Dimension Dimension Magnification Magnification Can View… Can view Quality of Detail Most Detail SEM SEM= =Scanning TEM TEM= =Transmission Electron Electron Microscope Scanning Transmission Microscope Electron Electron 2D 1000X Preserved… living General view 3D 500X Preserved… Used to dissect 3D 1000 to 10,000X Scans surface Preserved larger, thicker structures Microscope 2D 10,000 to 100,000X Transmits thru Preserved The Winner!!! smaller; more detai PROkaryotic vs EUkaryotic Cells Similarities & DNA, Cytoplasm, Membrane, Ribosomes 94 Cytoplasm Differences NUCLEUS, Complexity Golgi Body C.Membrane C.Wall DNA Nucelar Membrane NUCLEUS ER Ribosomes Mitochondria Plant Cell vs Animal Cell Similarities Nucleus & C.Membrane & Organelles & (except Chloroplast) Differences No C.Wall, No Chloroplast, Vacuole size, Shape Vacuole 95 ER Nucleus C.Wall Golgi Body Mitochondria C.Membrane ER Mitochondria CM Cytoplasm Vacuole Chloroplast Cytoplasm 1. What do you notice about the photograph that leads you to believe the cell is an animal cell? 2. What part of the cell is the pointer on? 3. Is this a prokaryotic or a eukaryotic cell? How do you know? Plant OR Animal?? 4. Can you label the parts? 5. Are these plant or Animal cells? Prokaryotic or Eukaryotic? 6. What kind of cells are these? 7. Are they prokaryotic or eukaryotic? 8. What is the dark spot near the middle? 9. What is the outer covering of these cells? 10. What kind of cells are these? 11. Are they prokaryotic or eukaryotic? 12. What are the small green structures? 13. What is the space circles in red? 1. 2. 3. Clear desk of EVERYTHING except for a pen/pencil AND a piece of paper for an answer sheet Read – Think – Understand – Answer - WRITE ANSWER to LEFT of NUMBER - Double-Check Turn in 4. Pick Up STUDY GUIDE FOR MAJORSum (omit question #2) 5. Finish Lab…. Microscope & Cell Lab • MICROSCOPE: – PART 1: Practice Using Letter ‘e’, Colored photograph, Foraminifera, Leech, Tapeworm Head for practice • MICRO-VIEWER: – PART 2 Cork Cells… they are dead plant cells! • Using Micro-Viewer…what Robert Hooke saw – PART 3 Plant Cells (Onion, Elodea) • Using Micro-Viewer – PART 4 Animal Cells (Cheek cells) • Using Micro-Viewer • LAB REPORT – due FRIDAY – – – – Title Purpose Data Conclusion HOMEWORK 1. MAJORSummtive TOMORROW Be the change you wish to see in the world
