The nucleus is the information center of the cell. It stores the cell's DNA and directs what the cell is doing. Usually, there is only one nucleus in a cell. Some of the things that the nucleus directs are cell division, growth, and protein synthesis. To learn more, click on

The nucleolus is an organelle that is made out of nucleic acids and proteins. Its main function is to make ribosomes inside the nucleus. Here is some more information, http://www.princeton.edu/~achaney/tmve/wiki100k/docs/Nucleolus.html.
Ribosomes are small structures that are either free or attached to each other. They are made out of proteins and RNA. Their function is to synthesize proteins inside the cell. More info can be found here, http://hyperphysics.phy-astr.gsu.edu/hbase/biology/ribosome.html.
Vacuoles are organelles in the cell that have no internal structure. They basically are pouches within the cell that hold fluids. The vacuole does not really do anything for the cell, but it acts more like a storage unit. To learn more, visit http://cfeil.tripod.com/vacuoles.htm.
