If the plasma membrane ruptures, the cell loses its contents to the surrounding environment, which can lead to cell death. The plasma membrane is crucial for maintaining the cell's internal environment and regulating what enters and exits the cell.

Consequences of a Ruptured Plasma Membrane
When a cell's plasma membrane ruptures, it leads to significant consequences that affect its viability. Here’s a detailed explanation of why option 'B' is correct:
Loss of Cellular Integrity
- The plasma membrane serves as a barrier that separates the interior of the cell from its external environment.
- A rupture compromises this barrier, allowing the uncontrolled flow of substances in and out of the cell.
Loss of Cellular Contents
- Essential components such as cytoplasm, organelles, and various biomolecules leak out of the cell.
- This loss disrupts metabolic processes and cellular functions, leading to a decline in the cell's ability to perform essential tasks.
Cell Death
- Without the necessary components and structural integrity, the cell cannot maintain homeostasis.
- The cell will ultimately undergo necrosis or apoptosis (programmed cell death) due to the inability to sustain life.
Inability to Repair
- While cells can sometimes repair minor membrane damages, a complete rupture generally exceeds their repair capabilities.
- The resources required for membrane synthesis may also be depleted following rupture, further preventing recovery.
In summary, a ruptured plasma membrane leads to the loss of cellular contents and ultimately results in cell death. This highlights the critical role of the plasma membrane in maintaining cellular health and functionality.
