Question

In a fully turgid cell, the values of DPD, OP and TP will show the tendency

• A. DPD$=$10atm, OP$=$15atm, TP$=$5atm
• B. DPD$=$5atm, OP$=$12atm, TP$=$7atm
• C. DPD$=$2atm, OP$=$7atm, TP$=$5atm
• D. DPD$=$0atm, OP$=$15atm, TP$=$15atm

Answer 1

Answer: (D)

DPD$=$0atm, OP$=$15atm, TP$=$15atm

In a fully turgid cell there will be no net movement of water. Neither water will move inside nor move outside. This is because DPD will be zero. DPD can be zero, when the osmotic pressure, which causes movement of water inside the cell equals to turgor pressure, which opposes the entry of water inside the cell.
