What is the difference between turgor pressure and wall pressure?
Turgor pressure:
The force within the cell that pushes the plasma membrane against the cell wall is known as turgor pressure.
Wall pressure:
The pressure placed on the contents of a plant cell by the cell wall that is equivalent to and opposite to the force of the turgor pressure is referred to as wall pressure.
Difference between turgor pressure and wall pressure:
Turgor pressure | Wall pressure |
1. The protoplasm exerts turgor pressure on the cell wall. | 1. The resistance to turgor pressure imposed by the cell wall. |
2. It has an effect on the cell wall. | 2. It is produced by the cell wall. |
3. The direction is towards the outside of the cell. | 3. The direction is towards the cell's interior. |
