Correct option is A
Ribosomes are the only organelles that are found both in eukaryotic and prokaryotic cells. They are responsible for protein synthesis and are present in the cytoplasm of both types of cells.
Ribosomes are composed of RNA and proteins and are essential for translating genetic information into functional proteins.
In eukaryotic cells, ribosomes are larger (80S) compared to those in prokaryotic cells (70S), but they serve the same function.
Prokaryotes rely heavily on ribosomes for protein synthesis, as they lack other complex organelles like the nucleus or mitochondria.
Additional Information:
Mitochondria: Found only in eukaryotic cells, mitochondria are the powerhouse of the cell, generating energy in the form of ATP.
Lysosomes: Present only in eukaryotic cells, lysosomes are involved in digestion and waste removal.
Endosomes: These membrane-bound organelles are found in eukaryotic cells and are involved in the trafficking of materials in and out of the cell.
