Stomata are pores that are unique to plants and found on the epidermis of most aerial tissues. Stomata act as gatekeepers to allow the entry of carbon dioxide (CO2) into the leaf for photosynthesis at the expense of water vapour loss via transpiration. Opening and closing of stomata is controlled by guard cells, which swell up and shrink as ions move in and out of them, respectively (Figure 1).
