Mesosome
Lysosome
Ribosome
Microsome
The ribosome is the site of protein synthesis. Mesosome is an extension of the cell membrane present in the cytoplasm as infolding and serves to increase surface area and as the site for cellular respiration in prokaryotes. Microsome refers to the fraction of ER studded with the ribosome. Lysosomes are the suicidal bags of the cell that have hydrolytic enzymes and serve to digest and remove the wear and tear organelles and molecules from the cell. Therefore, the correct answer is Lysosome.
