Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What will happen immediately if the cell membrane fails to function properly in a cell?
A
The cell will have difficulty moving materials into and out of the cell.
B
The cell will not be able to control all the activities occurring inside the cell.
C
The cell will not be able to produce enough energy for cellular processes.
D
The cell’s organelles will no longer be surrounded by a gel-like fluid.
Explanation: 

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: -A eukaryotic cell is separated from the extracellular environment by a plasma membrane composed of a phospholipid bilayer containing proteins that regulate transit of molecules into and out of the cell. Loss of this barrier function can lead to compromised cellular homeostasis and death of the cell.

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: -Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly.
