9.1.3 Explain the relationship between the distribution of tissues in the leaf and the functions of these tissues. Upper epidermis-Consists of a single layer of cells found on the upper surface of the leaf. It is covered by a thick waxy cuticle.The main function of the upper epidermis is water conservation.It prevents the loss of water from the upper surface where the light intensity and heat are the greatest.pongy mesophyll-Made up of loosely packed cells. This tissue is found in the lower half of the leaf (lower surface) and has few chloroplasts. It provides gas exchange (CO 2 uptake and O 2 release) and therefore needs to be close to the stomata found in the lower epidermis.
