The cell membrane is said to be selectively permeable because it lets certain substances pass through while restricting the passage of others. The actual structure of the cell membrane allows free passage or restricts movement of substances across the membrane. Cell membrane is selectively permeable (Semi-permeability- only let in some molecules inside the cell) because of its structure. Phospolipid bilayer, with some protein, is what makes the cell membrane selectively permeable.

Phospolipid bilayer, with some protein, is what makes the cell membrane selectively permeable. Cell membrane is made up of two sheets of phospolipid. The phospolipid has a hydrophilic head and a hydrophobic tail. A. selectively permeable means not letting anything in or out. B. selectively permeable means letting everything in and out.

This allows only certain particles to go through including water and leaving behind the solutes including salt and other contaminants. In the process of reverse osmosis, thin-film composite membranes (TFC or TFM) are used.
