Pressure can build up in a plant system when water enters a plant cell due to diffusion causing a pressure built up against the cell wall, it makes the cell turgid; this increases the pressure potential. Explain.

Dear student,
Water enters the cell through cell wall and membrane by the process of osmosis. Water builds up in the cell exerting pressure on the wall of the plant cell which is called pressure potential. This pressure is opposed by the pressure of the wall on the plasma membrane making the cell turgid which is very important for plant cell to maintain its turgidity, in absence of which plant loses its shape and wilts. Both the pressure is essential for maintaining turgidity.
