If the stomata remained closed all day,gases would not be exchanged.Therefore carbon dioxide levels within the leaf would decrease and oxygen levels would increase.As a result,photorespiration would increase in C₃ plants.CAM plants would be unaffected because they have adapted to living in hot,dry climates and they normally keep their stomata closed during the day.Since water enters a plant through the roots rather than the stomata,closing the stomata would not result in a decrease in the amount of water within the leaf.
