Answer to Question #139519 in Cell Biology for sam

Question

which structure of organelle is found in both prokaryotic and eukaryotic ?

Answer 1

• 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 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.
• The correct answer is 'Ribosome'.
