Explanation:

The organelles labeled E are ribosomes. Ribosomes are responsible for synthesizing proteins by assembling amino acids into polypeptide chains, which matches one of the options. The other options describe functions of other organelles: digestion of old parts is lysosomes, regulating cell entry/exit is the cell membrane, and storing water is vacuoles.

They produce proteins for the cell.
