leaf
The leaves are composed of epidermal tissue, tissue mast (palisade), parenchymal tissue, tissue carriers (xylem and phloem). Parenchymal tissue of the leaf there are 2 styles of palisade parenchyma tissue within the type of a pole or fence and spongy parenchyma tissue of the sponge tissue, that each contain chlorophyll. Leaf epidermal tissue cells are changed into the mouth of the leaves (stomata). as a result of it is the location of leaf photosynthesis (the network poles and sponge tissue), web site of the respiratory or respiration and evaporation or transpiration (through the mouth or the stomata of leaves). Transport network within the leaves may be a continuation of the network carrier on the trunk and roots.
