Detailed explanation-1: -The cell wall is the outermost layer of a plant cell. It makes the cell stiff and gives it protection. Animal cells do not have cell walls.
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: -Cellulose makes the cell wall of plant cells rigid.
