The investigation of the structure of cells began with magnifying glasses and then microscopes, which consisted of a combination of lenses, greatly increased the magnifying power.

There are two types of microscopes that can be used - the light and electron microscopes (TRANSMISSION AND SCANNING)

Click onto the different types of microscopes and see what they look like. There is also extra information on other types of microscopes. Then proceed with the study guide below.

• The Light Microscope -
• and the electron microscope - (transmission and scanning).

• This is for those who have a real interest in the
  physics of microscopes.-
