What is the cell wall of fungi made of?
The cell wall of fungi is made of chitin and hemicellulose. Chitin, a polysaccharide, provides structural support and rigidity to the cell wall, while hemicellulose contributes to its strength and flexibility. This composition distinguishes fungal cell walls from those of plants and bacteria.

The cell wall of fungi is primarily composed of Option [D], chitin and hemicellulose. Chitin, a strong polysaccharide, forms the major structural component, providing rigidity and support to fungal cells. Hemicellulose, another polysaccharide, contributes to the strength and flexibility of the cell wall. This unique composition distinguishes fungal cell walls from those of other organisms. Unlike plant cell walls, which contain cellulose, and bacterial cell walls, which contain peptidoglycan or other substances, fungal cell walls are characterized by the presence of chitin. This structural framework plays crucial roles in maintaining cell shape, protecting against environmental stresses, and facilitating nutrient uptake. Additionally, the composition of fungal cell walls influences interactions with other organisms and environmental factors, contributing to their ecological roles and impact on various ecosystems. Overall, chitin and hemicellulose are key components that define the distinctive architecture and function of fungal cell walls.
