Question : 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?

Answer»

<P>`{:("Root parenchyma",,"Root xylem"),(Psi_(p) "" Psi_(s),,Psi_(p)""Psi_(s)),("200-190",,"-2005"):}`
`{:("Root parenchyma",,"Root xylem"),(Psi_(p) "" Psi_(s),,Psi_(p)""Psi_(s)),("-200220",,"65-5"):}`
`{:("Root parenchyma",,"Root xylem"),(Psi_(p) "" Psi_(s),,Psi_(p)""Psi_(s)),("200-220",,"65-5"):}`
`{:("Root parenchyma",,"Root xylem"),(Psi_(p) "" Psi_(s),,Psi_(p)""Psi_(s)),("200-220",,"-65-5"):}`
