The main component of the cell wall in plants is cellulose. Cellulose is a complex carbohydrate or polysaccharide that gives rigidity and structural support to the plant cell wall, allowing plants to maintain their shape and withstand various physical stresses. This substance is composed of long chains of glucose molecules linked together, forming microfibrils that provide strength. The cell wall also contains other components such as hemicellulose and lignin, which further enhance its durability. In addition to providing structural support, the cell wall regulates cellular growth and transport of substances.
