Leaf Structure And Function Youtube Structure of the leaf | plant | biology | the fuseschoolplants make food through photosynthesis. using their leaves, plants combine sunlight, carbon dioxide. Leaf structure and function. the outermost layer of the leaf is the epidermis; it is present on both sides of the leaf and is called the upper and lower epidermis, respectively. botanists call the upper side the adaxial surface (or adaxis) and the lower side the abaxial surface (or abaxis). the epidermis helps in the regulation of gas exchange. Figure 30.10.1 30.10. 1: trichomes: trichomes give leaves a fuzzy appearance as in this (a) sundew (drosera sp.). leaf trichomes include (b) branched trichomes on the leaf of arabidopsis lyrata and (c) multibranched trichomes on a mature quercus marilandica leaf. below the epidermis of dicot leaves are layers of cells known as the mesophyll, or. Figure 35.5.3.1 35.5.3. 1: mesophyll: (a) (top) the central mesophyll is sandwiched between an upper and lower epidermis. the mesophyll has two layers: an upper palisade layer and a lower spongy layer. stomata on the leaf underside allow gas exchange. a waxy cuticle covers all aerial surfaces of land plants to minimize water loss.
