Situated at the top of the leaf near the epidermis' source of light. 1 of 6 Adaptations of : upper epidermis A relatively transparent layer of cells which allows light through to the palisade cells. 2 of 6 Adaptations of : stoma These pores on the lower epidermis allow oxygen, water vapour & carbon dioxide to diffuse out. 3 of 6 Adaptations of : guard cells These specialised cells change their shape to open or close the stoma. 4 of 6 Adaptations of : waxy cuticle This layer reduces water loss from the leaf by evaporation by blocking the stomata and is a barrier to the entry of pathogenic MOs. 5 of 6 Adaptations of : spongy mesophyll This layer of cells is loosely packed, giving a large SA for gas exchange. 6 of 6
