Detailed explanation-1: -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-2: -The cell wall provides strength and structural support to the cell, and can control to some extent what types and concentrations of molecules enter and leave the cell. The materials that make up the cell wall differ depending on the type of organism.
Detailed explanation-3: -Provides structural support. Protection against infection and mechanical stress. Separates interior of the cell from the outer environment. It enables transport of substances and information from the cell insides to the exterior and vice versa.
