| Parenchyma | Collenchyma | Sclerenchyma |
|---|---|---|
| The cells of the parenchyma have thin walls made of cellulose. | The cells of this tissue have cell walls thickened at the corners due to cellulose deposition. | The walls of sclerenchymatous cells are thickened due to lignin deposition. |
2.
