What are the properties of the cell wall and membrane?

The cell membrane is a two-layer (two layers of molecules of the lipid class) membrane of the cell, through which various substances pass into and out of the cell. Those. the cell membrane metabolizes substances with the environment. The cell membrane is capable of repairing damaged areas, which ensures the safety of the cell’s integrity.

The cell wall is much stronger than the membrane, therefore it performs a mechanical function, maintaining the constant shape of the cell and creating a “barrier” from neighboring cells. In the process of cell growth, it stretches and grows with it, because has elasticity. It is in the cell membrane that water and inorganic substances dissolved in it move.
