A selectively permeable membrane.
The cell membrane only allows certain molecules through.
The cell membrane is called as semi-permeable membrane because it allows only certain/selective molecules to pass through it.It mostly allows only solvent molecules to pass.It is sometimes also called as selectively permeable membrane.
water molecules are smaller than corn syrup. the membrane allows a certain size of molecules.
There are antibodies and cell-surface receptors and enzymes; is there a more specific A. in view?
semi-permeable.

A "semi permeable" membrane.
I semi-permeable membrane is a membrane when only certain substances can pass through it.it is a membrane that will only allow certain molecules through it . in general oxygen , food and water are allowed to enter ; waste products are allowed to exit and harmful substances are kept out. hope this helps.
