A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", [2][3] while the leaves, stem, flower, and fruit collectively form the shoot system. [4] .
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.

As one of the most important constituents of plants, leaves have several essential functions: The primary function of the leaf is the conversion of carbon dioxide, water, and UV light into sugar (e.g., glucose) via photosynthesis (shown below).
The meaning of LEAVES is plural of leaf.
Leaves are highly efficient solar energy converters. They capture light energy and through the process of photosynthesis. They are able to trap energy in the form of sugar molecules that are constructed from carbon dioxide and water (both found in the atmosphere).
Ginkgo tree leaves have palmate venation. The veins fork, then travel a bit, then fork again, travel, fork, and so on until the veins reach the margin (edge) of the leaf. Sugar maple leaves have a classic palmate venation with five lobes. Photo by Matt Lavin, CC BY-SA 2.0. Left: Corn leaves have parallel veins. Center: A leaf with netted veins.
Leaves have many structures that prevent water loss, transport compounds, aid in gas exchange, and protect the plant as a whole.
Leaves are the main sites for photosynthesis: the process by which plants synthesize food. Most leaves are usually green, due to the presence of chlorophyll in the leaf cells. However, some leaves may have different colors, caused by other plant pigments that mask the green chlorophyll.
