stomatal regulation
Leaf breathing management
Stomatal regulation is the process by which plants control the opening and closing of stomata—tiny pores on leaf surfaces that allow gas exchange.
Plants balance competing needs: opening stomata admits carbon dioxide for photosynthesis but loses water through transpiration.
Environmental factors like light, humidity, and carbon dioxide levels trigger guard cells to swell or shrink, adjusting the aperture: Drought stress triggers stomatal regulation that conserves water.
