  • microscopes let us see things that we can't see with the naked eye.
  • light microscopes use light and lenses to form an image and magnify it.
  • light microscopes let us see individual cells and large subcellular structures.
  • electron microscopes use electrons instead of light to form an image.
  • electron microscopes have a much higher magnification and a higher resolution than light microscopes.
  • electron microscopes let us see much smaller things like the internal structures of subcellular structures like mitochondria
  • resolution is the ability to distinguish between two points, so a higher resolution gives a sharper, clearer image.
  • magnification= image size/ real size
  • 1000 micrometre = 1 millimetres
