A leaf cell contains chloroplast that is exposed to light to initiate the process of photosynthesis. Other important functions include storage of food and water. However, in some plants the functions of the leaves are modified for certain other purposes. A few of the leaf types are vegetables included in the human diet. Below is a simple classification of leaves based upon their shapes.

A leaf is an organ of a vascular plant and is the principal lateral appendage of the stem.

The plant leaves are lateral outgrowth of the stem which develop from the meristematic tissues of buds. They are the part of the plant shoot which serves as the chief food-producing organ in most vascular plants. To perform this function more efficiently, they are arranged on the stem and oriented as to allow maximum absorption of sunlight. It is also via leaves that loss of water from the plant body primarily occurs through the process of stomatal transpiration and in guttation. The leaves may be considered as the most important life-giving part of the plant body. This organic compound contains the energy which the plant obtains from the sun, the same energy that powers animal and human life.

Leaf , in botany , any usually flattened green outgrowth from the stem of a vascular plant. As the primary sites of photosynthesis , leaves manufacture food for plants, which in turn ultimately nourish and sustain all land animals. Botanically, leaves are an integral part of the stem system, and they are initiated in the apical bud growing tip of a stem along with the tissues of the stem itself. Certain organs that are superficially very different from the usual green leaf are formed in the same manner and are actually modified leaves; among these are the sharp spines of cacti , the needles of pines and other conifers , and the scales of an asparagus stalk or a lily bulb. Typically, a leaf consists of a broad expanded blade the lamina , attached to the plant stem by a stalklike petiole. Leaves are, however, quite diverse in size, shape, and various other characteristics, including the nature of the blade margin and the type of venation arrangement of veins.
