If the plasma membrane were to break down, it would be catastrophic for the cell. Think of the membrane as the cell's skin and its security guard, all in one. It maintains a stable internal environment by controlling everything that enters and leaves.

Without that barrier, the cell’s contents, like its cytoplasm and organelles, would spill out. At the same time, the outside environment would rush in uncontrollably. This complete loss of regulation means the cell can no longer function. It would lose its structure and essential chemical balance, leading to its very quick death, likely by bursting.
