Question

In a cell, why does diffusion pressure decrease, on addition of solutes?
Given, diffusion pressure deficit = osmotic pressure - turgid pressure​

Answer 1

Explanation:

If some solute is dissolved in water, its diffusion pressure decreases. The difference between diffusion pressure of pure water and solution is called diffusion pressure deficit (DPD). When a plant cell is placed in a hypotonic solution, water enters into a cell by osmosis and as a result turgor pressure develops.
