Microscopy

• What type of microscope is commonly used in classrooms?

  Light microscope
• What is a key advantage of light microscopes?

  They are small, easy to use, and cheap
• What limits the resolution of light microscopes?

  They rely on light with a wavelength of 0.2 micrometers
• What types of structures can light microscopes not effectively study?

  Sub-cellular structures like mitochondria
• What are the characteristics of electron microscopes?

  They are large, expensive, and hard to use
• What is the benefit of using electrons in electron microscopes?

  Electrons have a wavelength of 0.1 nanometers
• How does the resolution of electron microscopes compare to light microscopes?

  Electron microscopes have 2,000 times better resolution
• Why is a smaller resolution value better?

  It allows seeing tinier details
• What can electron microscopes be used to study effectively?

  Sub-cellular structures like mitochondria
• What type of image can be obtained from an electron microscope?

  Images with much higher magnifications
• What are the pros and cons of light and electron microscopes?

  Light Microscopes:

  • Pros: Small, easy to use, cheap
  • Cons: Limited resolution (0.2 micrometers)

  
  

  Electron Microscopes:

  • Pros: High resolution (0.1 nanometers), can study sub-cellular structures
  • Cons: Large, expensive, hard to use
