Cacti grow slowly due to the fact that they keep their stomata closed for much of the day. Why would closing their stomata during the day be an advantage for the cacti? A. it limits water loss through transpiration B. it conserves oxygen produced in photosynthesis C. it recycles carbon dioxide within plant systems D. it protects plant tissues from predators
Based on my understanding of your question, your correct answer to this question would beit limits water loss through transpiration. There would only be so much that the stomata would do.
