Q.2. If the organisation of a cell is destroyed due to some physical or chemical influence, what will happen?
Ans. Each living cell has the capacity to perform certain basic functions due to its cell organelles which are responsible for its organisation. If this organisation of a cell is destroyed, then cell will not be able to perform certain basic functions and ultimately it will die soon.
Q.3. Why are lysosomes known as suicide bags ?
Ans. Lysosomes contain powerful digestive enzymes capable of breaking down all organic material whenever there is disturbance in the cellular metabolism, i.e., when the cell gets damaged, then these lysosomes may burst and the enzymes digest their own cell. Therefore, lysosomes are also known as the ‘suicide bags’ of a cell.
