Which outcome minimizes osmotic stress to succulents undergoing excessive transpiration via opened stomata?

💡 Explanation

Abscisic acid induces stomatal closure, minimizing water loss and therefore osmotic stress, rather than increased water uptake alone because root absorption capacity might lag behind transpiration demands whereas ABA swiftly regulates stomatal apertures.
