One of the main roles of a cell membrane is to absorb nutrients from the surrounding environment. In order to do this, the cell membrane must have proteins that detect the presence of molecules that should be taken into the cell.
For these cells, the cell membrane also manages the movement of water, CO2 and oxygen in and out of the cell, and for all plant and animal cells the membrane is usually selectively permeable to specific preferred ions and organic molecules, and has lipid-protein complexes embedded in it to assist in the transfer of other molecules into the cell that the membrane is not initially permeable to.
