What do the cell walls of fungi contain?

• A. Cellulose
• B. Peptidoglycan
• C. Chitin
• D. Lignin

Answer: (C)

Verified step by step guidance

1. Understand that cell walls are structural layers surrounding some types of cells, providing protection and support.
2. Recognize that different organisms have cell walls made of different materials. For example, plant cell walls are primarily made of cellulose.
3. Identify that fungi are a distinct group of organisms, separate from plants and bacteria, and have unique cell wall compositions.
4. Learn that the cell walls of fungi contain chitin, a long-chain polymer of a N-acetylglucosamine, which is a derivative of glucose.
5. Note that chitin provides structural strength to fungal cell walls, similar to how cellulose provides strength to plant cell walls.
