Introduction:-
The leaf is a green flat thin expanded lateral appendage of stem which is borne at a node and bears a bud in its axil . It is exogenous in origin and develops from the leaf primordium of shoot apex.The green colour of leaf is due to presence of the photosynthesis pigment chlorophyll which helps plants to synthesize organic food.
The green photosynthesis leaves of a plant are collectively called foliage.They are borne on stem in acropetal succession.
