The cell `A` has an osmotic potential of `-20` bars and a pressure potential of `+6` bars. What will be its water potential?

A

`-14bars`

B

`+14bars`

C

`-20bars`

D

`-26bar`

Text Solution

Verified by Experts

The correct Answer is:
A
`Psi_(w)=Psi_(s)+Psi_(rho)`
Where `Psi_(w)=`water potential ,`Psi_(s)=` osmotic potential
and `Psi_(rho)=` pressure potential
`Psi_(w)=(-20)+(+6)=-14` "bars"`
