Which of the following results would be more likely if a cell's membrane was no longer selectively permeable?

A. Harmful substances can enter the cell and cause mutations in the cell's DNA.

B. The cell would die because it could not regulate what substances could enter and leave.

C. A cell wall would form outside the membrane to protect the cell contents.

D. The cell would grow as more nutrients could easily enter the cell.

The correct answer is B the cell would die because it could not regulate what substance could enter or leave.

Explanation:

Plasma membrane of the cell is generally semipermeable in nature. In simple words it means that plasma membrane only allow specific or selective substance to pass across itself.

Plasma membrane generally allow non polar substances to pass through it but restrict the entry of polar substances and ions.

But if the plasma losses its semipermesble nature then any molecule can enter the cell which is not needed or which can be toxic for the cell.

As a result normal cellular homeostasis is being hampered and the cell dies.
