Usually,
only the cell's nucleus is visible through a light microscope.  In plant cells, the cell wall
and vacuole may also be visible.  However, there are many cell parts (also called organelles)
that are too small to be seen through a light microscope.  Three examples of these organelles
are...

ribosomes - synthesize protein for the
cell

endoplasmic reticulum - transport protein
throughout the cell

mitochondria - produce
energy for the cell

These cell parts can be viewed using a more powerful type
of microscope called an electron microscope .
