Explanation:

- Mitochondria: Known as the powerhouse of the cell. They generate energy in the form of ATP but are not involved in breaking down cell components.

- Vacuole: Mainly found in plant cells. They store nutrients, waste products, and help maintain pressure but do not digest cell materials.

- Ribosome: These are involved in protein synthesis. They translate genetic information into proteins and are not involved in cellular self-destruction.

- Lysosome: Lysosomes contain digestive enzymes. They break down worn-out cell parts and foreign invaders. Because they can digest the entire cell if they burst, they are called the ‘suicide bag’ of the cell.
