Vedclass · Answer

(B) During the day,transpiration is the primary force driving water upward in plants. However,at night,when stomata are closed and transpiration is minimal or absent,water is transported upward primarily due to root pressure. Root pressure is generated by the active accumulation of ions from the soil into the vascular tissue of the roots,which creates an osmotic gradient that draws water into the xylem.
