what would you if cell membrane became impermeable instead of selectively permeable could cell remain alive

If a cell membrane became impermeable, instead of selectively permeable, the cell would not remain alive, though certain organisms would be able to stay alive longer than others. This is because the cell membrane allows essential molecules and substances such as oxygen into the cell, while allowing harmful substances, like waste, out of the cell.

If the cell membrane becomes impermeable rather than being selectively permeable, both the needed and unwanted materials would enter into the cell of a living organism, which would lead to its death.

A cell membrane can be defined as a cell organelle that acts as the wall of a cell and it typically controls what enters or leaves the cell of a living organism.

Generally, a cell membrane is selectively permeable in nature and some of its functions include:

It allows materials that are needed by a living organism to enter the cell.

It serves as a shield (wall) for the cell’s internal parts.

It preserves the environment inside the cell by preventing it from changing.

It allows unwanted materials to leave (exit) the cell of a living organism.

Assuming the cell membrane becomes impermeable rather than being selectively permeable, both the needed and unwanted materials would enter into the cell of a living organism.

In conclusion, a cell with an impermeable rather than a selectively permeable cell membrane would not remain alive.
