The organelle known as the suicidal bag of the cell is the

Explanation

Lysosomes hold hydrolytic enzymes at an acidic pH, and if the membrane ruptures those enzymes digest the cell itself, a process called autolysis. This is deliberate during development, for example when the tail of a tadpole is removed. Peroxisomes also contain enzymes but they handle hydrogen peroxide and fatty acid oxidation rather than wholesale digestion.
