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.
semi-permeable.
The cell membrane only allows certain molecules through.
Semi- Permeable
It allows only certain molecules to pass through.
The Plasma Membrane, which has a phospholipid bi-layer.
permiable
It allows only certain molecules to pass through.
When a cell's membrane is permeable, it means that only certain proteins and other molecules can go in and out of the porous membrane, through protein pumps and other pathways. Some molecules stay inside the cell, while others float outside. Starches, for example, are large molecules that cannot pass through the membrane.
A membrane, such as the cell membrane, which allows only certain types of molecules (usually small and non charged ones) to pass through it freeely.
