Q. Difference between osmotic pressure and turgor pressure is :
- DPD
- Transpiration pull
- Osmotic potential
- Solute potential
Solution :
Correct option : A The difference between osmotic pressure and turgor pressure gives the diffusion pressure deficit. Mathematically, DPD= Osmotic pressure (OP) – Turgor pressure (TP). DPD is the pressure difference between pure water and solution. Osmotic pressure is the minimum pressure that needs to be applied on the solution to prevent the inward flow of its pure solvent across a semipermeable membrane and turgor pressure is the pressure inside the cell pushes plasma membrane against the cell wall of the plant cell.
