Final answer:
The fluidity of the cell membrane is advantageous because it allows for essential cellular processes and prevents disasters such as cell bursting due to osmotic disruption.
Step-by-step explanation:
The crystallization of a cell membrane would be disastrous because the cell membrane needs to be fluid for it to function properly. The fluidity of the cell membrane allows it to carry out important processes such as the movement of molecules in and out of the cell, cell signaling, and maintaining the integrity of the cell. If the cell membrane were to crystallize, it would become rigid and lose its ability to perform these essential functions.
One example of why a fluid cell membrane is necessary is osmosis, the diffusion of water. If the cell membrane were crystallized, it would not be able to undergo expansion and would not be able to stretch. This means that if the cell were exposed to pure water or water that is purer than the fluid inside the cell, it would continuously take on water until it bursts, resulting in cell death. The presence of a cell wall outside the membrane can prevent this disaster because it resists expansion and allows the cell to pressurize, preventing excessive water entry.
In summary, the fluidity of the cell membrane is advantageous because it allows for essential cellular processes and prevents disasters such as cell bursting due to osmotic disruption. Crystallization of the cell membrane would hinder its ability to function properly and lead to detrimental consequences for the cell.
