Question

what happens of plasma membrane ruptures or breaks?​

Answer 1

$\huge\red{\mid{\fbox{\tt{Answer}}\mid}}$

If the plasma membrane ruptures or breakdown then the cell will not be able to exchange material from its surrounding by diffusion or osmosis. Thereafter the protoplasmic material will be disappeared and the cell will die.

Answer 2

Answer:

Plasma membrane serves as selectively permeable barrier between cell component and the surroundings. It allows only selected material to move in and out of cell thereby maintains the cell's interior intact. Rupture or break down of plasma membrane would result in the exposure of cell component to the external environment and would ultimately result in cell death.
