The Plasma Membrane, which has a phospholipid bi-layer.
semi-permeable.
This might be a fundamental description of a semiconductor material.
The cell membrane only allows certain molecules through.
It allows only certain molecules to pass through.
Semi- Permeable
A selectively permeable membrane.
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.
permiable
The cell membrane only allows certain molecules through.
It allows only certain molecules to pass through.
the plasma membrane allows certain material to pass in and out.
A selectively permeable membrane only allows certain material to pass through it. They do so through active or passive transport.
