Life on earth depends upon gas exchange between shoots and the atmosphere. Carbon dioxide entry produces new carbohydrates in photosynthesis, and water evaporation cools the plant and the planet. These gases move through stomata which are epidermal valves made up of two guard cells around a pore. Stomata make gas exchange possible since valve opening and closing allows carbon dioxide entry while minimizing water loss.

地球上的生命依赖于嫩芽和大气之间的气体交换。二氧化碳进入会在光合作用中产生新的碳水化合物，而水的蒸发会使植物和地球降温。这些气体通过气孔移动，气孔是由毛孔周围的两个保卫细胞组成的表皮瓣膜。气孔使气体交换成为可能，因为阀门的打开和关闭允许二氧化碳进入，同时最大限度地减少水分损失。
