It is called "the gate keeper".

The term that describes the difference in concentrations of a substance across a cell's membrane is called the concentration gradient. This gradient drives the movement of substances such as ions or molecules across the membrane through processes like diffusion or active transport to achieve equilibrium.
The term that describes the cell plasma membrane is "phospholipid bilayer." This structure consists of two layers of phospholipids, with hydrophilic heads facing outward and hydrophobic tails facing inward, creating a semi-permeable barrier. The membrane also contains proteins, cholesterol, and carbohydrates, which contribute to its fluidity and functionality in regulating the movement of substances in and out of the cell.
