electron and light microscope

• What are the two types of microscopes discussed in the video?

  Light microscopes and electron microscopes
• Why are light microscopes considered conventional microscopes?


  Because they are commonly used in classrooms
• What are the advantages of light microscopes?


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


  0.2 micrometers
• What does a resolution of 0.2 micrometers imply about details smaller than this?


  They will appear blurry
• What type of cells can light microscopes be used to see?


  Individual cells like onion cells
• 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 just 0.1 nanometers
• What is the maximum resolution of electron microscopes?


  0.1 nanometers
• How does the resolution of electron microscopes compare to that of light microscopes?


  Electron microscopes have 2000 times better resolution
• Why is a smaller resolution value better?


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


  Sub-cellular structures like mitochondria
• What is a key difference in the images produced by light and electron microscopes?


  Electron microscopes provide images with much higher magnifications without blurriness
• What are the pros and cons of light microscopes and electron microscopes?


  Light Microscopes:

  • Pros: Small, easy to use, relatively 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
• What type of cell structure was shown in the image taken with an electron microscope?


  The nucleus and mitochondria
• What should you remember when comparing light and electron microscopes?


  The pros and cons of each type
• Where can you find practice questions on the topic of microscopes?
