Stomata, which are a key evolutionary adaptation of land plants, are also a visually accessible model system for analyzing how plant development progresses from cell proliferation, fate commitment, and the control of cell size, position, and shape. Life requires gas exchange between shoots and the atmosphere. CO2 entry yields new carbohydrates in photosynthesis, and H2O evaporation cools the plant and the planet. These gases move through stomata, epidermal valves made up of two guard cells around a pore whose opening and closing allows CO2 influx and minimizes water loss.

气孔是陆生植物进化适应的关键，也是一个直观的模型系统，用于分析植物发育如何从细胞增殖，命运承诺以及控制细胞大小，位置和形状。生命需要芽与大气之间的气体交换。CO2进入光合作用产生新的碳水化合物，H2O蒸发冷却植物和地球。这些气体通过气孔，表皮阀由两个保卫细胞组成，围绕一个孔，其打开和关闭允许CO2流入并最大限度地减少水分损失。
