  • Microscopes
    • Scanning Electron Microscopes
      • Negatives
        • Large
        • Very Expensive
        • Require a lot of skill and training to use
      • Benefits
        • Produces a 3D image
      • Resolution of 10nm
      • Magnificationof 15x to 200,000
      • How it works
        • Electrons bounce off the specimen's surface (NOT PASS THROUGH) and is focused on a screen. The specimen is coated in metal and vaccumed
          • Produces a black & white image BUT false colour can be added on the computer
    • Light Microscopes
      • Benefits
        • Easy to use
        • Relatively cheap
        • Portable
        • Can look at living specimens
      • Magnification of x1500 to x2000
      • Resolution of 200nm
      • Negatives
        • Can't see small organelles like ribosomes
    • Magnification
      • How much bigger an object becomes compared to the original much bigger an object becomes object
    • Resolution
      • The ability of a microscope to produce an image that shows fine detail clearly
    • Laser Scanning Microscopes
      • How it works
        • Laser light scans an object point by point then its reassembled by a computer to give one image
