Question:

What happens when a pressure greater than the atmospheric pressure is applied to pure water or a solution?

Solution:

The water potential of pure water or a solution increases on the application of pressure values more than atmospheric pressure. For example: when water diffuses into a plant cell, it causes pressure to build up against the cell wall. This makes the cell wall turgid. This pressure is termed as pressure potential and has a positive value.
