Moisture levels of the air and soil are other important factors. When … 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. nsis official site https://artificialsflowers.com
