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: -Cellulose is very strong, and the mesh that it forms in the cell wall forms a physical barrier to support the cell and maintain cell shape.
Detailed explanation-3: -It provides a structural framework to support plant growth and acts as the first line of defense when the plant encounters pathogens. The cell wall must also retain some flexibility, such that when subjected to developmental, biotic, or abiotic stimuli it can be rapidly remodeled in response.
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.
Detailed explanation-5: -Gives the cell a definite shape and structure. 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. More items
