The primary structural component responsible for most of the mechanical strength of the cell wall is cellulose . Cellulose is a complex carbohydrate, or polysaccharide, consisting of long chains of glucose molecules. These chains form microfibrils, which are strong and rigid, providing the cell wall with its tensile strength and structural integrity.
