2. Plant and animal cell structure

3.  3 types of microscopes  Light  Electron  Scanning/tunnelling

5.  Always carry with 2 hands  Only use lens paper for cleaning  Do not force knobs  Always store covered  Keep objects clear of desk and cords

6. Eyepiece Body Tube Revolving Nosepiece Arm Objective Lens Stage Stage Clips Coarse Focus Fine Focus Base Diaphragm Light

7.  Place the Slide on the Microscope  Use Stage Clips  Click Nosepiece to the lowest (shortest) setting  Look into the Eyepiece  Use the Coarse Focus

8.  Follow steps to focus using low power  Click the nosepiece to the longest objective  Do NOT use the Coarse Focusing Knob  Use the Fine Focus Knob to bring the slide What can you find on your slide?

9. 1. Set up the microscope to view the prepared slides 2. View at least 4 different slides, make a labelled diagram of what you see 3. Classify your cells as being either plant or animal cells 4. Write a simple experimental write up for this experiment

10.  Needs the following heading Aim: The purpose of the experiment Materials: A list of what was used Procedure: A step by step description of the process Results: Your labelled diagrams and any other observations Discussion: Analysis of results, include similarities and differences between animal and plant cells from your observations, include any errors of difficulties. Conclusion: Write a concluding paragraph about the results and the aim

11.  beams of electrons are used to produce images  wavelength of electron beam is much shorter than light, resulting in much higher resolution with this type of microscope

13.  uses electrons reflected from the surface of a specimen to create an image  produces a 3-dimensional image of specimen’s surface features
