The wall and plasma membrane regulate the kinds of materials that enter and leave the cell thus making it possible for the cell to maintain an identity different from its surroundings. The wall is not simply an inert substance providing strength and giving structure to plant cells as once was thought, but is active in several metabolic processes including absorption and secretion of substances, the detection of bacterial and fungal pathogens, and even regulation of growth and development. Cellulose, the most common material of plant cell walls, is a polysaccharide composed of long chains of glucose molecules that assume crystalline properties in the cell wall. During wall formation, adjacent cellulose molecules link together forming bundles called microfibrils. The microfibrils, in adjacent cellulose molecules link together forming bundles called microfibrils....
