Cards (17)

  • Why are light microscopes considered conventional microscopes?
    They are commonly used in classrooms
  • What are the advantages of light microscopes?
    They are small, easy to use, and cheap
  • What is the resolution limit of light microscopes?
    0.2 micrometers
  • What does a resolution of 0.2 micrometers mean?
    Details less than 0.2 micrometers appear blurry
  • What can light microscopes be used to observe?
    Individual cells like onion cells
  • What are the characteristics of electron microscopes?
    They are big, expensive, and hard to use
  • What is the benefit of using electrons in electron microscopes?
    Electrons have a wavelength of 0.1 nanometers
  • What is the maximum resolution of electron microscopes?
    0.1 nanometers
  • How does the resolution of electron microscopes compare to light microscopes?
    Electron microscopes have 2000 times better resolution
  • Why is a smaller resolution value better?
    It allows 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 higher magnifications
  • What are the pros and cons of light microscopes?
    Pros:
    • Small
    • Easy to use
    • Relatively cheap

    Cons:
    • Limited resolution (0.2 micrometers)
    • Not suitable for sub-cellular structures
  • What are the pros and cons of 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 electron microscope image?
    Nucleus and mitochondria
  • What should you remember when comparing light and electron microscopes?
    The pros and cons of each type
