- The question can be solved by using the difference between eukaryotic and prokaryotic cell.
- Prokaryotic cell does not have a well defined nucleus. The nuclear material lies naked in the cytoplasm. It is known as nucleoid. While, eukaryotic cell has a well defined nucleus with a nuclear membrane.
- Prokaryotic cell has a single chromosome while eukaryotic cell has more than one chromosome.
- Finally, prokaryotic cell do not have membrane-bound cell organelles while eukaryotic cell have membrane-bound cell organelles.
Hope you could get an idea from here.
