Question map
Which one of the following cell organelles is known as 'suicide bags' of a cell ?
Explanation
Lysosomes are membrane-bound organelles containing powerful hydrolytic enzymes capable of breaking down all organic materials [2]. They are commonly referred to as the 'suicide bags' or 'suicide sacs' of the cell because of their role in autolysis [1]. If a cell becomes damaged or reaches the end of its life cycle, the lysosomal membrane can rupture, releasing these digestive enzymes into the cytoplasm, which then digest the cell's own components, leading to programmed cell death or apoptosis [3]. While other organelles like mitochondria provide energy and plastids assist in photosynthesis or storage in plants, only lysosomes possess the specific autolytic function that earns them this nickname. They also play critical roles in destroying invading bacteria and recycling worn-out cell parts through a process known as autophagy [2].
