What happens when a pressure greater than the atmospheric pressure is applied to pure water or a solution? | NCERT solution | Class 11 Biology | Unit-11 Transport in Plants



Q.7:- What happens when a pressure greater than the atmospheric pressure is applied to pure water or a solution?

 

Answer:- 



If a pressure greater than atmospheric pressure is applied to pure water or a solution, its water potential increases. It is equivalent to pumping water from one place to another. 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.
