Which effect results when abscisic acid fails to activate?

A)Enhanced water loss from stomata
B)Activated phloem loading near roots
C)Decreased xylem osmotic pressure
D)Increased root cellular respiration

💡 Explanation

Higher water loss occurs due to uncontrolled transpiration; abscisic acid triggers stomatal closure via turgor pressure reduction mediated by potassium efflux. Consequently, reduced turgor stops closure rather than correctly closing, because ABA normally induces water conservation, thus water loss.
