The effect of nitrogen supply on the transpiration rate and stomatal opening of potted bean plants was studied in a series of experiments. The transpiration rates of N-supplied plants were higher than ...

Plant stomata are pores in the epidermis of plant leaves. They play a key role in regulating the gas-water exchange between the plant and the atmosphere, which enables photosynthesis and transpiration ...

Microscopic pores on the surface of leaves called stomata help plants “breathe” by controlling how much water they lose to evaporation. These stomatal pores also enable and control carbon dioxide ...
