Summary:
- Prokaryotic and eukaryotic cells have structures in common.
- All cells have a plasma membrane, ribosomes, cytoplasm, and DNA.
- The nucleus is where cells store their DNA, which is the genetic material.
- Prokaryotes do not have a nucleus.
- Instead, their DNA floats around inside the cell.
- Eukaryotes are single-celled (unicellular) organisms.
- Bacteria and Archaea are the only prokaryote.
