Scientists at the Carnegie Institution's Department of Global Ecology have changed the way researchers believed stomata regulate water vapor loss from a leaf. Studies have shown that radiation is the driving force of physical processes deep within the leaf.


Stomata are lip-shaped pores surrounded by a pair of guard cells that control the size of the opening. The size of the pores regulates the flow of carbon dioxide needed for photosynthesis and the outflow of water vapor to the atmosphere.
