A tiny, little-understood plant pore has enormous implications for weather forecasting, climate change, agriculture, hydrology, and more. Scientists have now overturned the conventional belief about how these important structures called stomata regulate water vapor loss from the leaf -- a process called transpiration. They found that radiation is the driving force of physical processes deep within the leaf.
