Explanation:

To solve this, we analyze each option:

• Plastic is a synthetic polymer, not biological or cellulose - based.
• Hair is mainly composed of keratin, a protein, not cellulose.
• Wood is a biological material, and the cell walls of plant cells (like in wood) are primarily made of cellulose.
