A cell membreces doesn't exist. If you mean cell membrane, then it is the surface of cells which separates the inside of the cell from the outside, facilitating the movement of particles and molecules to and from the cell.

Could it be that you mean cell membranes?

If that is the case, so here is an explanation: the cell membrane is the separation between the cytoplasma and the extracellular space. These membranes keep inter alia the organells in the cell which exist in the cytoplasma.

Adding onto this, the cell membrane is selectively permeable, meaning it control what enters and leaves the cell.

Right, but Eloades11 above me has mentioned it before.

Perhaps the thread starter is interest in an example? a well known one are proteins which are creating in ribosomes. And the ribosomes as a part of the endoplasmatic reticulum exist in the inner of the cell. After creating proteins, they are leaving the cell through the membrane to be used out of it.
