What is the difference between turgor pressure and wall pressure?
The movement of water into the cell is known as endosmosis. The phenomenon makes the plasma membrane to push towards the cell wall tightly. This results in turgor pressure and wall pressure.
The core difference between turgor pressure and wall pressure is that turgor pressure is the hydrostatic pressure developed against the cell wall due to endosmosis, while wall pressure is the pressure exerted by the cell wall against the turgor pressure.
What Is Turgor Pressure?
Turgor pressure is a type of force exerted by the cytoplasm towards the cell wall due to endosmosis. The pressure makes the cytoplasm increase in size. It plays a vital role in plant cells such as growth and enlargement of cells.
What is Wall Pressure?
Wall pressure is the force exerted by the cell wall to resists turgor pressure during endosmosis. It prevents the cell from expanding by pushing the cell wall towards the plasma membrane.
Comparison Chart: Turgor Pressure Vs Wall Pressure
| Basic Terms | Turgor Pressure | Wall Pressure |
| Meaning | The pressure exerted by protoplasm against the cell wall | The force exerted by the cell wall to resist turgor pressure |
| Cell wall | Act on the cell wall | Generated by the cell wall |
| Direction | Towards the outside of the cell | Towards the inside of the cell |
| Significance | Keep the plant in an upright posture, enhance the expansion of leaves and control opening and closing of stomata | Maintain the structure of the cells and plants |
Core Difference between Turgor Pressure and Wall Pressure
- Turgor pressure is the force exerted by protoplasm against the cell wall during endosmosis while wall pressure the force exerted by cell wall to resist turgor pressure
- Turgor pressure act on the cell wall while wall pressure is generated by cell wall
- Turgor pressure is exerted towards the outside while wall pressure towards the inside
- Turgor pressure keeps the plants in an upright position while wall pressure maintains the structure of the cells and plants.

Summary
The main difference between turgor pressure and wall pressure is that turgor pressure is the force generated by the cytoplasm towards the cell wall while wall pressure is the force generated by the cell wall towards the cytoplasm.
