|
The cell will not be able to control all the activities occurring inside the cell.

|
|
The cell will not be able to produce enough energy for cellular processes.

|
|
The cell’s organelles will no longer be surrounded by a gel-like fluid.

Detailed explanation-1: -Cell membrane regulates the diffusion or osmosis process of cell. Once cell membrane is broken the cell organelles leak out side and cell looses its identity. Also cell organelles can be easily infected by pathogens. Ultimately loss of cell membrane results in cell death.
Detailed explanation-2: -Loss of this barrier function can lead to compromised cellular homeostasis and death of the cell. Most cells are subjected to mechanical or chemical stresses that can disrupt the plasma membrane; thus there is strong selective pressure to ensure the integrity of this membrane.
Detailed explanation-3: -Once the plasma membrane ruptures, solutes from the exterior can harm the cell organelles which will lead to cell death.
Detailed explanation-4: -If our cells couldn’t control what crossed their membranes, either no molecules would make it across, or they’d be traveling willy-nilly and the internal environment would always be in flux.
Detailed explanation-5: -72 Membranes are Selectively Permeable In other words, plasma membranes are selectively permeable-they allow some substances through but not others (Figure 1). If the membrane were to lose this selectivity, the cell would no longer be able to maintain homeostasis, or to sustain itself, and it would be destroyed.
