A cell membrane is selectively permeable because it only allows particles to move across them due to different concentrations. Molecules move from areas of low concentration to high concentration.
Selective permeable
it is not selective permeable. - Cell membranes are selective permeable. Cell walls are fully permeable - which means that it allows all substances/molecules to pass in and out of the cell. It is located outside of the membrane.

The membrane at the boundary of every cell that acts as a selective barrier is called the cell membrane. The cell membrane is made of compounds called proteins and lipids.
means that the cell membrane has some control over what can cross it, so that only certain molecules either enter or leave the cell
Cell membrane is selectively permeable membrane, therefore it allows selective molecules to be taken in by the cell and excludes others. Whereas cell wall is permeable in nature and does not inhibit the intake of many molecules what the cell membrane does.
The cell membrane enables a cell to control what enters and leaves. The membrane has a selective semi-permeable membrane which facilitate this process.
Selectively permeable means that only certain substances are able pass through the cell membrane.A selectively permeable membrane is a membrane that only can be permeated by selective things, in other words a surface that lets some molecules in but not others. Like a cell membrane will let water diffuse into it :)
