In this article, we propose to discuss about the internal structure of leaf. The foliage leaves are characterised by green colour, thinness and flatness. They develop as protrusions from the shoot apex and are organs of limited growth. Leaves are very important vegetative organs, as they are chiefly concerned with the physiological process.
