StomataThere are tiny openings on the undersides of a leaf known as stomata. Air moves in and out of a leaf through these openings.
Yes, the stomata, which are pores in the lower epidermis of the leaf and are surrounded by 2 guard cells, open in the day to let in CO2 for photosynthesis but they also release H2O as water vapour and they close at night to reduce water loss.
The outer layer of the skin, the epidermis, consists mainly of cells called keratinocytes.
Amphistomatous describes a certain type of leaf morphology in drought adapted plants. These plants have stomates (the openings in the epidermis which allow CO2 to diffuse into the leaf) on both sides of the leaf.

The surface of the leaf that you see is the "epidermis".
The epidermis covers the lower and upper sides of the leaf.
