Detailed explanation-1: -Answer and Explanation: The main function of the cell membrane are to ensure to control the substances that are moving in and out of the cell.
Detailed explanation-2: -The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
Detailed explanation-3: -Cell wall is present outside the cell membrane. It has the function of giving shape and rigidity to the cell. Cell wall is present only in plants hence it is the characteristic feature that distinguishes between plant and animal cells.
Detailed explanation-4: -The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength shape, rigidity and structure to filter molecules that pass in and out of the cell.
