Vedclass · Answer

(B) Root pressure is a positive hydrostatic pressure that develops in the xylem of roots due to the active absorption of mineral ions. It is observed that root pressure is maximum during the night and early morning hours when the rate of transpiration is low or absent. Conversely,it is minimum or absent during the day when the rate of transpiration is high,as the water is pulled up by the transpirational pull. Therefore,the statement that root pressure is maximum during the day and minimum during the night is incorrect.
