In a flaccid cell

Water potential of a flaccid cell will be

Pressure potential in a plasmolysed cell is

The term, Psi_(p) , is called pressure potential or

Consider the following i. For a solution at atmospheric pressure Psi_(w)=Psi_(s) ii. Psi_(w) (water potential) of a cell is affected by solute potential only iii. Psi_(p) (pressure potential ) is usually positive in xylem during the day which of the statements given above is/are correct?

What would be the Psi_(P) of a flaccid cell ?

What would be the Phi_(P) of a flaccid cell?

On a warm summer day the transpiration pull is the main force that drives from root parenchyma into the root xylem. The table shows values of Psi_(rho) (pressure potential ) and Psi_(s) (solute potential) in root xylem and root parenchyma , in kPa. In which of the options (a-d) would tranpiration pull cause water to move from root parenchyma into the root xylem?
