This site has a very detailed information about a cell Nucleus. It also has pictures that will help you understand about a cell nucleus, however you should not use this link as your final information in a project.
this website was very useful in explaining the similarities and differences between nucleoli and ribosomes. I learned more than I thought i would on that website alone.
What they have in common:
They are both part of the "endomembrane system" and they are made up of phosholipid bilayer membrane.
How they differ:
The Endoplasmic Reticulum is bound with ribosmes, but the golgi body is not.
