Every breath we take connects us to the whole biosphere. It’s both fact and metaphor that tiny atoms of carbon, oxygen, and other elements flow from our lungs, out into the world, and back again. These atoms become part of clouds, other creatures, plants; they ride the wind.
One of the most remarkable turnstiles for these elements are stomata, a pair of cells which form an opening on plant leaves, stems, and flowers. Stomata draw in carbon dioxide from our breaths and other sources, and release water and oxygen in the service of plant growth and survival for all living things. Stomata show up in a stunning range of shapes, textures, and designs. They are humble, beautiful, exceptionally important structures worthy of celebration.
Diatoms, also called phytoplankton, are tiny plants that make over half of the planet’s oxygen.
