Question

(D) The water potential of a cell is given by the equation $\psi_{w} = \psi_{s} + \psi_{p}$.In a fully turgid cell,the pressure potential $(\psi_{p})$

Vedclass · Accepted Answer

$\psi_{w} = \psi_{s} + (\psi_{p})$ where $\psi_{p}$ is negative

Vedclass · Answer

(D) The water potential of a cell is given by the equation $\psi_{w} = \psi_{s} + \psi_{p}$.In a fully turgid cell,the pressure potential $(\psi_{p})$ is positive.However,in a plasmolysed cell,the protoplast shrinks away from the cell wall,resulting in a negative pressure potential $(\psi_{p} Therefore,the expression for the water potential of a plasmolysed cell is $\psi_{w} = \psi_{s} + \psi_{p}$,where $\psi_{p}$ is negative.

The correct expression for the water potential of a plasmolysed cell is:

Explain: Water Potential.

$A-$ Positive value of turgor pressure is called ${\Psi _P}$.
$R-$ The more the solute molecules,the lower (more negative) is the ${\Psi _S}$.

Water potential is denoted by $..........$.

Choose the correct option:
$(1)$ The value of ${\psi _S}$ is always negative / positive.
