In a fully turgid cell

Answer: BSolution: In case of fully turgid cell, the net movement of water into the cells is stopped. the cell is in equilibrium with the water outside. the water potential in such a case will be zero (0).
A cell at full turgor its osmotic potential and pressure potential equal but opposite in sign. Therefore, its water potential will be zero. For example a cell has its ${\psi }_s$ of - 10 bars and ${\psi }_p$ fo 10 bar, the resultant water potential will be zero as follows: ${\psi }_w={\psi }_s+{\psi }_p$
${\psi }_w=-$10 bars + 10 bars
${\psi }_w=0$ bars
