Question

Cell organelle present in both prokaryotic and eukaryotic cells is

• A. Ribosome
• B. E.R.
• C. Mitochondria
• D. Nucleus

Answer 1

The correct option is A Ribosome

• The difference between a prokaryotic and eukaryotic cell is that a prokaryotic cell does not contain a well-defined nucleus or membrane-bound organelles as found in a eukaryotic cell.
• Therefore, a prokaryotic cell lacks E.R, mitochondria and nucleus.
• But it contains ribosomes (70S type) which are known as the protein factories because they are the main site of protein synthesis and are made up of ribonucleic acids and proteins.
• So, the correct answer is 'Ribosome'.
