← Nature & AnimalsWhich consequence results when endodermal casparian strips are non-functional in plant roots?
A)Uncontrolled water loss occurs rapidly✓
B)Nutrient uptake becomes highly selective
C)Xylem sap maintains lower tension
D)Transpiration rates decrease significantly then stop
💡 Explanation
Uncontrolled loss results because the non-functional casparian strip allows apoplastic water movement. Bypassing selective cellular uptake causes unregulated release; therefore uncontrolled loss occurs rather than controlled mineral ion uptake because selective transport won't function in the stele.
