Which outcome occurs when a plant adapts Crassulacean Acid Metabolism (CAM) in an extremely arid environment?

💡 Explanation

When CAM plants face aridity, they utilize temporal separation by opening stomata at night during cooler temperatures via osmoregulation to minimize water loss and carbon dioxide uptake, initiating initial carbon fixation. Therefore stomata open at night, rather than increasing efficiency, transport, or pigmentation, processes irrelevant in the extreme dessication conditions of the question.
