the cell is fully turgid when one of the foolowing condition fulfilled

1. diffusion pressure deficit= turgor pressure
2. diffusion pressure deficit=suction pressure
3. osmotic pressure = diffusion pressure deficit
4. diffusion pressure deficit=zero

Hello Student
Correct answer is 4. Diffusion pressure deficit = zero
In a fully turgid cell, diffusion pressure deficit=zero
As, Turgor pressure = osmotic pressure.
