12 Important Cell wall Function

1. Cell wall provides the cell a sense of organization.
2. It maintains and  gives a distinctive shape to the cell.

8. By limiting water intake,the cell wall prevents cell growth.
9. It also prevents cell water loss due to the presence of Cutin and suberin.
10. It controls the direction of cell growth.
11. The cell wall helps to maintain the osmolarity of the cell.
12. The cell wall stores carbohydrates in the seed.
