stomata
Stomata are microscopic pores in the epidermis of leaves and stems, each flanked by a pair of guard cells that open and close to regulate gas exchange with the atmosphere. By controlling the influx of carbon dioxide for photosynthesis and the efflux of water vapor through transpiration, these structures play a central role in plant productivity, water-use efficiency, and drought resilience. Studying stomatal development and function also offers insights into how plants evolved to balance the competing demands of carbon gain and water conservation.
