Detailed explanation-1: -When stomata are open, however, water vapor is lost to the external environment, increasing the rate of transpiration. Therefore, plants must maintain a balance between gas exchange and water loss. Water stress, high temperatures, and high carbon dioxide concentration causes stomata to close.
Detailed explanation-2: -When stomata are open, water vapor and other gases, such as oxygen, are released into the atmosphere through them. A number of factors can affect the exchange of gases between a leaf and the atmosphere.
Detailed explanation-3: -Transpiration helps in transportation of absorbed minerals to all the parts of the plant. Transpiration provides water for the process of photosynthesis. Transpiration helps in cooling the structures of the plant when exposed to hot sunlight.
