Get On Task I will complete a lab comparing cells Cells TOPIC: Tues 11.28.12 TOPIC: MY GOAL: Get On Task I will complete a lab comparing cells REVIEW ISN pages 88 - 95

Do you know what these do…? Protective outer covering of a plant, fungus, or bacterial cell Contains genetic instructions Transport channels Used for photosynthesis Jelly-like substance where chemical reactions take place Helps to maintain homeostasis in cells; outside of animal cells Make proteins Coverts energy in food to usable energy Control center of cell Packaging area of cell Contains enzymes Transport pocket Cell wall………….. DNA…………………… ER…………………….. Chloroplast……... Cytoplasm………. Cell membrane...... Ribosomes……….. Mitochondrion... Nucleus……………. Golgi body……….. Lysosome…………. Vesicle……………..

Think about this…. 1st can you identify the organelles and 2nd Can you Work out a pathway from the Nucleus to the Cell Membrane that would keep a protein from ever entering the Cytoplasm Nucleus to ER Vesicle Golgi Cell Membrane

Using the Micro-Viewer

The Compound light microscope Stage down On LOW power Slide on Bring course adj. up FOCUS DOWN using course adj Switch to Med. Pwr using course adj. Then switch to high pwr using Fine Adj ONLY http://www.youtube.com/watch?v=bGBgABLEV4g&feature=related&safety_mode=true&persist_safety_mode=1&safe=active

Practice Focusing the Scope Use the Prepared “e” slide & a color photo with WHITE in the photo - it’s kind of cool! Red = L Yellow = M Blue = H COURSE Adj Fine Adj

Microscope & Cell Lab PART 1 Using The Microscope PART 2 Cork Cells Stations up front looking at the letter ‘e’ Colored photograph…. For fun! Foraminifera… for fun PART 2 Cork Cells Using Micro-Viewer…what Robert Hooke saw PART 3 Plant Cells (Onion, then Elodea) Using Micro-Viewer PART 4 Animal Cells (Cheek cells) Culminate with LAB REPORT – due FRIDAY Title Purpose Data Conclusion

Look how the letter ‘e’ is placed on the stage! LOW – Course Adjustment MEDIUM - Course & maybe Fine HIGH- Fine ONLY!

What you will basically see CORK CELLS ONION CELLS ELODEA CELLS CHEEK CELLS

Before you leave… Your area should be left the way you found or a little better…! Please pick up any trash in your area… yes, even if it is not yours… that would be the right thing to do Push chairs under tables. Thank you for your help with keeping OUR room clean & organized – I DO APPRECIATE IT!
