• Light microscopes


  Microscopes that use light, small, easy to use, relatively cheap
• Resolution of light microscopes

  Limited to 0.2 micrometers, any details less than 0.2 micrometers apart will appear blurry
• What light microscopes can be used to see

  • Individual cells like onion cells
• Electron microscopes


  Really big, very expensive, hard to use, only used by scientists in laboratories
• Resolution of electron microscopes

  Maximum resolution of 0.1 nanometers, 2000 times better than light microscopes
• What electron microscopes can be used to study

  • Sub-cellular structures like mitochondria
• Electron microscopes can give images with much higher magnifications without going blurry
• Light microscopes


  Pros: small, easy to use, relatively cheap. Cons: limited resolution
• Electron microscopes


  Pros: very high resolution. Cons: big, expensive, hard to use
