Explanation:

Prokaryotic cells are simple, lacking membrane - bound organelles. Mitochondria are membrane - bound organelles (they are part of the endomembrane system and have a double - membrane structure), so they are not present in prokaryotic cells. Ribosomes (non - membrane - bound, used for protein synthesis), cell membrane (a phospholipid bilayer that encloses the cell), cytoplasm (the gel - like substance inside the cell), and the combination of cell membrane and ribosomes are all found in prokaryotic cells.

Answer:

A. mitochondria
