Stomata

Stomata are microscopic pores found on the surface of plant leaves that are important for the exchange of gases including carbon dioxide, oxygen, and water vapor. Through stomata, plants can both take in carbon dioxide to use in photosynthesis and release oxygen that is a product of photosynthesis. As such, stomata are essential for the survival of plants and, ultimately, of the earth’s atmosphere and climate. Through their modulation of gas exchange, plants regulate their water loss and in doing so, protect themselves from dehydration. Stomata, therefore, play an essential role in the health of plants, and ultimately the health of the planet.
