What is the arrangement of molecules in a cell wall?

The cell wall is primarily composed of cellulose in plants, chitin in fungi, and peptidoglycan in bacteria. These molecules are arranged in a rigid, organized structure, providing support and protection to the cell. In plant cell walls, cellulose fibers are arranged in a network that allows for flexibility while maintaining strength. This arrangement helps to withstand turgor pressure and contributes to the overall integrity of the cell.
