A membrane that permits the passage of only certain molecules is called a semi-permeable membrane.
In its simplest form, this separation process is based on molecular size. Smaller molecules pass through and larger ones are retained.
In most biochemical processes, a concentration gradient drives the movement of molecules through the membrane.

Specific Semi permeable membrane
The cell membrane
The cell membrane only allows certain molecules through.
the cell membrane allows only certain substances to pass through it It is considered semipermeable because, it allows non charged particals to pass through.
A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.The things that can easily move in and out of the cell through the membrane are gases, like oxygen and carbon dioxide, and water.
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.
Which statements describe the cell membrane? Check all that apply. It only allows certain materials to leave the cell. It allows all materials to leave the cell. It only allows certain materials to enter the cell. It allows all materials to enter the cell. It helps the cell get rid of waste. It brings waste into the cell for storage.
