Which effect accelerates when a plant's stomata remain consistently open in arid conditions?

A)Increased xylem water transport efficiency
B)Enhanced root turgor pressure maintenance
C)Dehydration-induced reduction of photosynthesis
D)Improved carbon dioxide fixation at night

💡 Explanation

Increased water loss drives dehydration and reduces photosynthesis because transpiration surpasses water uptake, leading to closure of stomata mediated by abscisic acid; therefore stomatal opening decreases photosynthesis, rather than increasing water transport which demands stomatal closure.
