What feature is found in eukaryotic cells but not in prokaryotic cells?

Eukaryotic cell contains membrane bound cell organelles such as Mitochondria, Nuclear Membrane, Endoplasmic Reticulum, Golgi apparatus, Plasma Membrane. Cell membrane gives structural rigidity and plays an important role in cellular trafficking i.e. allowing substances in and out.

Prokaryotic cell doesnot have any membrane bound cell organelles and hence there is an absence of cellular trafficking check. Their structures are simple and easy to understand their mechanism. They undergo frequent mutation where as Eukaryotic cells doesn't.
