Detailed explanation-2: -Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection.

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: -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.
