Q. Whose water potential is less than water potential of root hair during the water absorption by root hair?
A) Gravitational water
B) Soil solution
C) Pure water
D) Vacuolar sap
Explanation
Water always moves from area of high water potential to area of low water potential, i.e., from less negative to more negative. During water absorption by root hair, the water movement is possible if water potential of vacuolar sap is lower than root hair.
