What is the difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have a nucleus, while eukaryotic cells do not.

• Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have them.

• Eukaryotic cells are always larger than prokaryotic cells.

• Prokaryotic cells are more complex than eukaryotic cells.
