The given statement is False.

The bacterial cells walls are composed of peptidoglycan, also known as murein. It comprises polysaccharide chains cross-linked by unusual peptides, involving D-amino acids. The bacterial cell walls are distinct from cell walls of fungi and plants that are made up of chitin and cellulose, respectively.

The cell walls in bacteria allow small molecules to pass through them freely, however, do not permit large molecules to pass through them, in this manner, it function as a coarse filter.

The main function of the cells wall is to sustain the shape of the cell and inhibit the cell from bursting due to osmotic pressure. The cell wall allows the components to pass, which are essential for bacterial nutrition.
