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.
The Lower epidermis is similar to the upper epidermis in the formation and structure. However, occurrence of stomata and trichomes may differ according to the species and environmental conditions. Stomata are abundant in the lower epidermis of a dorsiventral leaf.pecial features exhibited by the epidermis are; the layer of cutin, guard cells, stomata, and trichomes. Both upper and lower epidermal cells secrete a waxy layer called cuticle. This layer helps to reduce the evaporation from leaves.
