A light microscope is sufficient to see the shape of the cell and its nucleus.  However, to see the smaller organelles, you would want to use an electron microscope.

Electrons are fired into a vacuum sealed container.  A positively charged electrode accelerates the electrons into a beam.  The electron beam passes through an electromagnetic coil, which focuses the beam on the specimen.  The electrons bounce off the specimen and into a detector, which then interprets the data into a magnified image.
