How is a prokaryotic cell different from a eukaryotic cell?
Answer:
The differences between a prokaryotic and eukaryotic cell are:
- A prokaryotic cell is a unicellular, primitive , simple type of cell characterised by the absence of a nucleus .
- Prokaryotes do not have membrane-bound cell organelles .
- Since Prokaryotes have no nucleus, their DNA is scattered throughout the cell .
- For Example - Bacteria, Archaea
- Eukaryotic cells are cells that possess a nucleus .
- They have membrane-bound organelles .
- The DNA is contained in the nucleus .
- Eukaryotes can either be unicellular or multicellular .
- For example - Plants , Animals , Fungi etc.
