Detailed explanation-1: -Plasma membrane controls the flow of substances in and out of cell.

Detailed explanation-2: -The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Detailed explanation-3: -What Do Membranes Do? Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly.

Detailed explanation-4: -The cell membrane is made up of a lipid bilayer with embedded proteins. It uses simple diffusion to control the movement of the substances. Some substances, such as proteins or glucose, are not able to pass through the membrane. This is what makes it semi-permeable.
