Explain why prokaryotic cells are generally smaller than eukaryotic cells.

• Prokaryotic cells have more complex structures.

• Prokaryotic cells lack a nucleus and membrane-bound organelles, making them simpler and smaller.

• Eukaryotic cells are smaller because they have a nucleus.

• Prokaryotic cells are larger because they have more DNA.
