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.
The cell membrane only allows certain molecules through.
That is a semi-permeable membrane.
It allows only certain molecules to pass through.
We define Osmosis as the passage of water from a dilute solution via a membrane which is semi permeable to a more concentrate solution. It means that Semi permeable membrane is a very thin layer of material which allows some molecule to pass through them and prevent some molecule from pass through them. These molecules are decided by the type of solution. Generally, the membrane only allows movement of H2O molecules. So, if on one side is a saturated solution of something while on the other side is a dilute solution, the movement of molecules will be from both the directions but net result will be from saturated to dilute solution.

a partially permeable membrane allows some molecules or ions to pass through it

Semi permeable membrane means a very thin layer of material which allows some molecule to pass through them and prevent some molecule to pass through them. Osmosis is the passage of water from a dilute solution via a membrane which is semi permeable to a more concentrate solution. So the membrane should be semi-permeable so as to only allow the movement of H2O molecules and not the other molecules of the mixture.
