Epidermal cells are important to the leaf because depending on the climate that the plant resides within, the plant may create more than one epidermal layer. The purpose of this/these layer is to retain water, and some plants have a cuticle formed on the outside of the epidermis to prevent the loss of water too. In order to bring in CO2 from the air, leaves contain stoma which are essentially small pores in the lower epidermal layer that can open or close based on the plants needs. Guard cells on each side of stoma regulate gas exchange, as well as the loss of water.
Epidermis
Is the Epidermis
Cell walls
The lower epidermis of the elodea leaf has the largest cell.
The surface of the leaf that you see is the "epidermis".
the outside layer of flat cells is the epidermis.
Palisade cells are typically found in the upper layer of a leaf called the palisade mesophyll. They are located directly beneath the upper epidermis and are responsible for carrying out photosynthesis due to their high concentration of chloroplasts.
It is a thin layer of translucent rectangular cells that form the outer layer of the leaves, protecting the inner layers of the leaf

tissues are layers of similar cells. the outside layer of a leaf is called the epidermis tissue. the epidermis is made of flat cells . this layer is like the top layer of your skin. it protects the plant.
in the stomata
Mesophyll In between upper and lower epidermis of leaf is mesophyll tissue. In the dorsiventral leaves, mesophyll is divisible into upper palisade cells and lower spongy parenchyma. The palisade cells are mainly involved in photosynthesis and spongy parenchyma in gaseous exchange.
