2 marks
Why does increased transpiration rate increase the rate of water uptake by roots?
A
Greater transpiration creates more tension pulling water up xylem — increased gradient drives faster uptake by roots
B
Transpiration has no direct effect on root water uptake
C
Increased transpiration reduces water uptake to conserve water
D
Transpiration pushes water downward from leaves to roots
