A
Protects the cell
B
Makes energy for the cell to use
C
Lets substances in and out of the cell
D
Provides support so cells can stand upright
E
Makes proteins for plant cells to use and grow
Explanation: 

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: -Withstand turgor pressure: Turgor pressure is the force exerted against the cell wall as the contents of the cell push the plasma membrane against the cell wall. This pressure helps a plant to remain rigid and erect, but can also cause a cell to rupture.

Detailed explanation-3: -The main function of the Cell Wall is to protect and provide support for the cell.

Detailed explanation-4: -Cell wall gives shape and support to the plant cell. Cell wall can hold the plant cells together and this will provide strength to the plant. Cell wall provide protection to plant cells from changing climatic conditions.

Detailed explanation-5: -In the cell wall, the pectins form a gel-like network that is interlocked with the crosslinked cellulose microfibrils. In addition, cell walls contain a variety of glycoproteins that are incorporated into the matrix and are thought to provide further structural support.
