Ribosomes, the cellular organelles responsible for protein synthesis, are produced by the nucleolus inside the cell. The nucleolus is a subcompartment within the cell nucleus that is involved in ribosomal RNA (rRNA) synthesis and ribosome biogenesis. The other options are not correct because lysosomes are involved in cellular waste digestion, endoplasmic reticulum is involved in protein synthesis and lipid metabolism, and mitochondria are responsible for energy production within the cell.
