Question

what is one polysaccharide in the cell wall besides cellulose? galactose starch pectin

To solve this, we analyze each option:

• Galactose is a monosaccharide, not a polysaccharide, so it's incorrect.
• Starch is a polysaccharide but is mainly for energy storage in plants, not a primary cell wall component besides cellulose.
• Pectin is a polysaccharide and is part of the plant cell wall structure, along with cellulose.
