Yes, it is true. The cell wall of different organisms differs in their composition.
Cell walls exist in all kingdoms except for the animals: plants, protists (algae), fungi, bacteria, and archaea. And in all these, the cell wall is made of different materials and composition.
Example:
| Type of cell |
Composition |
| Plant cell wall |
Cellulose, pectin, lignin |
| Bacterial cell walls |
cellulose and polysaccharides |
| Archaeal cell walls |
Pseudo-peptidoglycan |
| Fungal cell walls |
Chitin |
