Gatekeepers: "Show Me the Carbon."
Tremendous concern is expressed in contemporary media about the increase of greenhouse gases, especially carbon, in our atmosphere. Rarely considered are the plants impacted by these gases, particularly since over 25% of all carbon is taken up by plants. The stomata of leaves serve as guard cells that allow carbon dioxide into the plant, and additionally, release oxygen and water. With an increase of carbon in the atmosphere, there are fewer (and larger) stomata. This process points to a singular, silent intelligence of plants that are busily adapting to climate change while we argue and prevaricate. Mysteries remain about the delicate balance between plants and the atmosphere, and how stomata (like harbingers) behave. This series examines micrographs of the humble, indispensable stomata and celebrates their diverse shapes and beauty.
