when a cell is fully turgid which of the following will be zero ?
1.Water potential
2. Turgor pressure
3. Wall pressure
4. Osmotic pressure
Explain with reasons

Option 1 is correct 

When cell is fully turgid water potential becomes zero

The net movement of water into the cell is stopped. The cell is in equilibrium with the water outside. Consequently the water potential in this case becomes zero.

Water potential    =    osmotic potential   +   pressure potential.
