The cell wall in plants is a rigid, protective layer surrounding the plasma membrane, primarily composed of cellulose, hemicellulose, pectin, and lignin. It provides structural support, maintaining the shape of plant cells and enabling plants to withstand turgor pressure generated by water within the cell. This rigidity allows plants to grow upright and form complex tissues and organs. The cell wall also acts as a barrier against mechanical injury and pathogenic organisms, protecting the cell from infection and environmental stress. It regulates the movement of water, ions, and molecules into and out of the cell,
