Why is the plasma membrane called a selectively permeable membrane?

Answer 1

The Plasma Membrane is a selectively permeable membrane as it only allows entry and exit of some selected molecules into and out of the Cells.

It also prevents movement of some other materials, therefore the plasma membrane is called a selectively permeable membrane.

Answer 2

The plasma membrane is called selectively permeable because it allows some substances to pass through while preventing others from entering or leaving the cell. This selectivity is achieved through the presence of specific transport proteins in the membrane that regulate the movement of molecules based on their size, charge, and solubility.

Answer 3

Because it permits only selected substances to pass through it.

Only water can pass through whenever it wants, viruses cannot pass through unless it hides behind something.

Answer 4

because it only allows specific molecules to enter and exit the cell. (that is what selectively permeable is)

Answer 5

The membranes only allow (or select) what goes in and out.
