    Under a light microscope, cells look a bit like this...
                                 X 100 mag
           What type of cell is this? Why?
   Under an electron microscope…

                 Light passes through the specimen and                           Passes a beam of electrons through the 
                 then through the magnifying lenses so                                    specimen to magnify it 
                    you can see the object much bigger

                 Much cheaper but lower magnifcation                                Gives a higher resolution.

   A light microscope shows us 
   bacteria don't have a nucleus
   An electron microscope shows 
    us that bacteria have two 
    types of DNA, chromosomal 
     and plasmid DNA.
