Cell membranes allow some molecules to move freely across the membrane, while

other molecules are restricted. Which term BEST describes this capability of a cell

membrane?

A. semipermeable

B.

impervious

C.

resilient

D. unyielding

Semi permeable membrane

A. semipermeable

Explanation:

The plasma membrane is semipermeable because it has the property of selective permeability, which controls the entry and exit of substances in the cell.

In other words, it is as if the plasma membrane acts as a filter, allowing smaller substances to enter, as well as making it difficult for larger substances to pass through.

Substances such as excretion and carbon dioxide come out as water, oxygen and food enter. The selective permeability process is essential for maintaining metabolic processes in cells.
