Question

"OP and DPD are equivalent in a flaccid cell". Give reason.

Answer 1

In a fully turgid cell, the value of DPD is equal to zero and turgor pressure is numerically equal to osmotic pressure. In a flaccid cell the turgor pressure is zero and hence, DPD will be equal to the osmotic pressurPressure potential refers to the positive pressure developed in a cell due to the entry of water through osmosis. ... 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.When the flaccid cell is placed in water then the pure solvent is water, the cytoplasm of the cell is solution and the sell membrane is semi permeable membrane.
