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.
Osmosis is the diffusion of water across a cell membrane. It is an essential process in cell membrane functioning. Whether or not a cell contains a rigid cellular wall or not will determine how it reacts to hypotonic and hypertonic solutions.iological cell membranes are selectively permeable, which means that the ease and rate of small molecules passing through membranes vary widely. The plasma membrane regulates exchange of nutrients, oxygen, inorganic ions, waste products, and water. The cellular membraneâs molecular organization controls permeability.
