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.
