Solution
The correct option is D Zero
Pressure potential refers to the positive pressure developed in a cell due to the entry of water through osmosis. In a turgid cell, the pressure potential is usually positive because water enters into the protoplast that generates turgor pressure. The pressure potential of a flaccid cell is usually zero because the water potential and pressure potential within a flaccid cell is equal. Thus, the pressure potential of a flaccid cell would be zero.
