Detailed explanation-1: -The pressure of the cell contents on the cell wall is called wall pressure and the pressure exerted by the cell wall on the cell content is called turgor pressure.

Detailed explanation-2: -turgor, Pressure exerted by fluid in a cell that presses the cell membrane against the cell wall. Turgor is what makes living plant tissue rigid. Loss of turgor, resulting from the loss of water from plant cells, causes flowers and leaves to wilt.

Detailed explanation-3: -Therefore, pressure exerted by the protoplasm against the cell wall in the cell is called turgor pressure.

Detailed explanation-4: -’Wall pressure’ is the pressure exerted by the cell wall to balance turgor pressure.

Detailed explanation-5: -When a plant cell is stretched fully due to turgidity, the cell wall exerts a counter-pressure on the contents of the cell. This pressure is known as the wall pressure.
