Since, the upper leaf blade is directly faced to the sun, the rate of transpiration increases. Hence, to prevent excessive transpiration, stomata are more in lower surface i.e. relatively less transpiration happens from the lower epidermis. Plants also remove water in the form of (liquid), this is guttation.
Water Vapor, CO2 and O2 pass through stomata. The Stomata are located on the underside of the leaf (lower epidermus) in order to prevent water loss from direct sunlight via ev â¦ aporation. The upperside (spper epidermus) of the leaf prevents water loss by evaporation.
