Answer:
Cellulose gives strength to cell. 
Explanation: 
Cellulose is a type of polysaccharide which is present in the cell wall of plant. It provides strength to the cell. It also helps in the absorption of water molecules from the surrounding environment. 
Cellulose is composed of 44.44% of carbon atom, 6.17% hydrogen atom, and 49.39% oxygen atom. The chemical formula of cellulose is (C6H10O5)n.
