  3. Lysosomes Lysosomes are a kind of waste disposal system of the cell. It cleans the cell by digesting any foreign material as well as worn-out cell organelles. Lysosomes are able to do this because they contain powerful digestive enzymes capable of breaking down all organic material

  4. Suicide bags During the disturbance in cellular metabolism, when the cell gets damaged, lysosomes may burst and the enzymes digest their own cell Therefore, lysosomes are also known as suicide bags. They are also known as scavengers and cellular housekeepers. Lysosomes are membrane-bound sacs filled with digestive enzymes These enzymes are made by RER.

  5. Vacuoles Vacuoles are storage sacs for solid or liquid contents. vacuoles are small sized in animal cells while plant cells have very large vacuoles vacuoles in plant cells may occupy 50%-90% of the cell volume. Vacuoles are full of cell sap and provide turgidity and rigidity to the cell Many substances are stored in vacuoles including amino acids, sugars, various organic acids and some proteins.

  7. Functions Vacuoles help to maintain the osmotic pressure in a cell. They store toxic metabolic by-products or end products of plant cells. They provide turgidity and rigidity and to the plant cells.
