The characteristic of this plant organ is that it is a dorsoventrally flattened organ, usually borne above the ground, and specialised for its function of photosynthesis. Photosynthesis is the process of converting the intake of carbonic acid gas into oxygen. The primary photosynthesis tissue, in most leaves, called palisade mesophyll, is located on the upper side of the blade operating room lamina of the leaf. However in that location are tranquillize exceptions, like in some species, including the mature leaf of Eucalypts, palisade mesophyll is present on both sides and these leaves are said to be isobilateral.
Many leaves give a distinct superior surface, alias adaxial and defined lower superficial called abaxial which differ in colour, the number of stomata ( stomata are the pores present happening leaves that intake and output gases), hairiness, the amount and structure of epicuticular wax and separate features. When talking about the coloring material of leaves, they are mostly fleeceable, but there are always exceptions.
