SSC MTS EXAM

Detailed explanation-1: -The main function of the cell wall is to provide structural strength and support, and also provide a semi-permeable surface for molecules to pass in and out of the cell. 3. Name other organisms besides plants to have a cell wall.

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: -Gravity resistance is a principal graviresponse in plants. The cell wall is responsible for the final step of gravity resistance. The gravity signal increases the rigidity of the cell wall. Changes in cell wall metabolism and environment bring about the rigidity change.

Detailed explanation-4: -It provides protection to the cell and prevents from any physical damage. It provides structure to the cell. It prevents from osmotic bursting. It protects the protoplasm against mechanical injury.
