According to one vital force theory, ascent of sap is due to acitve pulsation of innermost layer of cortex. This theory was give by In plant 'transpiration pull' theory for ascent of sap was first proposed by

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?

Mineral salts are translocated through (i) along with the (ii) steam of water. Which is pulled up through the plant by transpirational pull. Fill up the bhlanks in the given statements and select the correct option
