Tiny, pore-like openings primarily found on the underside of plant leaves that play a crucial role in gas exchange and transpiration. Each stoma (singular for stomata) is surrounded by specialized guard cells that open and close the pore to regulate the movement of carbon dioxide, oxygen, and water vapor in and out of the plant. In cannabis cultivation, stomata are essential for photosynthesis and respiration, impacting the plant’s overall health and growth.
