Which option is true for a fully turgid cell ?

Options

A. `OP=DPD`
B. `OP=Zero`
C. `DPD=Zero`
D. `TP=zero`

Answer

C

Explanation

As the cell becomes fully turgid the value of turgor pressure becomes equal to that of solute potential `(Psi_(s))` so that water potential `(Psi_(w))` or `DPD` becomes either zero or equal to that of external hypotonic solution.
`Psi_(w)=Psi_(s)+Psi_(rho)=0`
Though there is no net movement of water between the cell and its environment, equilibrium is dynamic and not static Equal exchange of water molecules continues between the cell and its environment.
