Which process maximizes water conservation in CAM plants during hot, dry daylight hours?

💡 Explanation

When daytime conditions are hot and dry, CAM plants exhibit temporal separation because they close their stomata during the day to reduce transpiration and subsequent water loss. Therefore stomata are closed, rather than remaining open or relying on root absorption or carbohydrate processes, which would increase water loss.
