Stomata as a Proxy for Atmospheric CO2 Levels

These strange, mouth-like structures are called stomata. Stomata are specialized pore structures found on plant leaves that permit the exchange of gases such as CO2, O2 and H2O, between the inside and outside of the leaf. They do so through the opening and closing of stomatal guard cells.

Plants convert visible light into sugars via the process of photosynthesis, which uses CO2 as a reactant. Along with light availability and temperature, CO2 is a limiting reactant of photosynthesis which means that the quantity of this compound controls the number of reactions that can take place.
