Detailed explanation-1: -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-2: -Cell membrane regulates the entry and exit of molecules from inside to outside of the cell and outside to inside of the cell.

Detailed explanation-3: -The plasma membrane is selectively permeable; it regulates what passes from one side to the other. A selectively permeable membrane will allow water to flow freely while limiting the passage of molecules, especially large molecules or those with a charge.
