Meaning
A prokaryotic cell is a simple cell which contains no membrane bound organelles.
About Prokaryotic Cells
- Prokaryotic cells include bacteria and some types of algae.
- Prokaryotic cells have a loop of DNA floating freely in the cytoplasm.
- Prokaryotic cells have no nucleus, mitochondria or chloroplasts.
- Prokaryotic cells are usually much smaller than eukaryotic cells.
- In the three domain system prokaryotes include both bacteria and archaea.
Examples
 |
| A diagram showing an E.coli bacterium which is a prokaryote. |
