The guard cells open and close the stomata as needed.

close
Yes, during a drought, plants close their stomata to conserve water and prevent excessive water loss through transpiration. This helps the plant maintain its hydration levels and survive the dry conditions.
Stomata close under strong sunlight to prevent excessive water loss through transpiration and to protect the plant from drying out. Closing the stomata reduces the amount of water vapor that can escape from the leaf surface, helping the plant conserve water.
Their stomata during the day!.
the guard cells
Changes in the osmotic potential of gaurd cells make that stomata open or closed
When the stomata in a leaf close during the day, it helps to reduce water loss through transpiration and conserves water within the plant. However, it can also limit the entry of carbon dioxide for photosynthesis, potentially slowing down the plant's growth and metabolism.
