Unlike prokaryotic cells (bacteria), eukaryotic cells have a nucleus. Their structure is often characteristic of their function; for example, neurons have a very different structural organization of enterocytes and a different function.
In the eukaryotic cell there are also organelles that are part of the endo-membrane system, or part of closed organelles (peroxisomes, mitochondria and chloroplasts).
