Cellulose/chitin/peptidoglycan (murein) are all carbohydrates so the cell walls contain the most polysaccharides

Polysaccharides are long chains of carbohydrates and with this comes many bonds which are strong. By having large polysaccharide molecules in the cell wall there is structural support as those glycosidic bonds require quite a lot of energy to break.
