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.
Also, water vapor is released into the atmosphere through these pores in a process called transpiration. Dicotyledons usually have more stomata on the lower epidermis than the upper epidermis. As these leaves are held horizontally, upper epidermis is directly illuminated.Locating fewer stomata on the upper epidermis can then prevent excess water loss.lso, water vapor is released into the atmosphere through these pores in a process called transpiration. Dicotyledons usually have more stomata on the lower epidermis than the upper epidermis. As these leaves are held horizontally, upper epidermis is directly illuminated.
