← Nature & AnimalsWhich outcome occurs when plant root endodermis dysfunction prevents controlled ion uptake?
A)Reduced xylem water potential gradients✓
B)Increased leaf boundary layer thickness
C)Elevated phloem osmotic pressure buildup
D)Enhanced stomatal closing response time
💡 Explanation
Dysfunctional endodermis disrupts ion regulation used to establish water potential gradients. Water uptake decreases because pressure in the xylem rises due to lack of ion import, therefore the gradient falls rather than increasing, which promotes leaf turgor.
