No, the upper epidermis is covered by a cuticle.
The upper epidermis is responsible for preventing water loss by evaporation. It does this by having a waxy cuticle on the top of the leaf. The lower epidermis has stomata, which allow gases to enter and leave the leaf as a result of photosynthesis and respiration.
In dicot plants the lower epidermis is frequently ruptured by stomata and thus helps in gaseous exchange and transpiration.
Removing the lower epidermis layer allows for easier observation of stomata and overall leaf structure. Stomata are mostly located on the lower epidermis, which regulates gas exchange for photosynthesis. Additionally, removing the upper epidermis may damage the leaf's cuticle, which can affect its ability to retain water.
The waxy coating the epidermis in a plant secretes is called a cuticle.
