Stomata close at midday to prevent excessive water loss through transpiration. During the hottest part of the day, the plant can lose a significant amount of water through open stomata, which can lead to dehydration and wilting. By closing the stomata, the plant can conserve water and maintain its turgidity, allowing it to survive the heat and dry conditions. Additionally, closing the stomata can also help to regulate the exchange of gases, such as carbon dioxide and oxygen, within the plant. **
