Q

Explain what you know about light microscope

A
  • Uses light to produce image
  • lower resolution than electron microscope
    -Used to look at whole cells or tissues
    -Used to view both living and non-living cells
    -Resolution = 200 nm
    -Magnification = x1500

Q

How does transmission electron microscope work

A

Transmission electron microscope uses electromagnets to focus of beam of electrons, which is then transmitted through the image to form a 2D image
