← Nature & AnimalsWhich consequence results when stomata malfunction, decreasing transpiration rate in trees?
A)Increased xylem sap cavitation risk
B)Enhanced leaf photosynthesis efficacy
C)Reduced mineral nutrient availability✓
D)Stimulated abscisic acid root synthesis
💡 Explanation
Reduced stomatal function decreases the trees' transpiration pull causing reduced mineral absorption in roots; because mass flow is required, therefore mineral nutrient availability is limited rather than photosynthesis, which responds primarily to light and CO2.
