Cytology the study of cells Robert Hooke - observed cork could float - discovered a honeycomb-like structure in a cork slice using a primitive compound microscope - only saw cell walls as this was dead tissue - coined the term "cell" for these individual compartments he saw Two types of microscopes: 1. Light Microscope 2. Electron Microscope Light Microscope - light is focused on specimen by a glass condenser lens - the image is magnified by an objective lens and an ocular lens - proj...

all organisms are made of cells and come from cells Cell theory When the cell size (INCREASES or DECREASES), the membrane gets smaller compared to cell volume. increases the study of cells Cytology "how can cork float" Took sections, looked under microscope and found that they had tiny chambers (aka cells) Robert Hooke Part of electromagnetic spectrum via sun, delivering energy that can be recorded as wavelengths (convert into color - ROY G BIV: red, orange, yellow, green, blue, indig...

3. Place slide on the microscope stage. 4. Select lowest power objective (x4) 5. Turn coarse adjustment knob to move lens towards slide. Stop turning once lens almost touches the slide. Look from side not eyepiece. 6. Look down eyepiece. Turn coarse adjustment knob until cells come into focus. 7. Slowly turn fine adjustment knob to bring more focus to cells. 8. Now can change to a higher power lens. Use fine objective knob. 8. Draw cells you can see using pencil. Label. Add a scale line ...
