The main difference between prokaryotic and eukaryotic cells is that only eukaryotic cells have a nucleus.
Prokaryotic cells, such as bacteria, do not have a membrane-bound nucleus or organelles, while eukaryotic cells, which include plants, animals, fungi, and protists, have a defined nucleus and various membrane-bound organelles. The other statements are incorrect:
- Prokaryotic cells do have a cell membrane.
- Prokaryotic cells are typically smaller than eukaryotic cells.
- Eukaryotic cells do have organelles.
