What is the main factor that determines the direction in which water moves across a plant's root hairs?
Concentration gradient of minerals
Water potential gradient
Pressure exerted by the xylem
Temperature
Explanation
Water moves from an area of higher water potential to an area of lower water potential, which is the driving force across the plant's root hairs.
