What would happen if the plasma membrane ruptures or breaks down?

Answer : This is the outermost covering of the cell that separates the contents of the cell from its external environment. The plasma membrane allows or permits the entry and exit of some materials in and out of the cell. It also prevents movement of some other materials. Thus, the cell membrane, acts like a selectively permeable membrane which regulates the movement of materials between the ordered interior of the cell and the outer environment.
In case, if it gets ruptured and broken, lysosomes may burst and the enzymes digest their own cell. Structurally, lysosomes are membrane-bound sacs filled with digestive enzymes. Lysosomes are a kind of waste disposal system of the cell. Lysosomes help to keep the cell clean by digesting any foreign material as well as worn-out cell organelles.
