Cell A with O P = 6 and W P = 5 is surrounded by the cells with O P = 3 and T P = 2 , what will be the direction of water movement?
Options
- AFrom A to other cells
- BFrom other cells to A
- CNo movement
- DWater will move up
Correct answer
C. No movement
Step-by-step solution
DPD is a diffusion pressure deficit and it is used to find out the direction of movement of water. The movement of water will take place from low DPD to high DPD and it can be calculated through given formula i.e. D P D = Osmotic pressure-Turgor pressure Cell A Cell B O P = 6 O P = 3 T P = W P = 5 T P = W P = 2 So D P D = 6 - 5 = 1 D P D = 3 - 2 = 1 The DPD of both the cells is coming equal. So there will be no movement of water.
