WebAug 15, 2024 · Stomata are open during the day because this is when photosynthesis typically occurs. In photosynthesis, plants use carbon dioxide, water, and sunlight to produce glucose, water, and oxygen. Glucose is used as a food source, while oxygen and water vapor escape through open stomata into the surrounding environment.

WebPlants in moist environments would require more stomata. This is because “Plants move water from soils to leaves through a passive evapotranspiration process which provides more hydrogen ions for photosynthesis.” (Boyer, 2015). Therefore, water movement is completely reliant on stomata density and water availability.
