The term leaf usually means an organ of a vascular plant. Many leaves are large, flat, green structures above ground, involved in photosynthesis. However many types of leaves lack one or more of these general characteristics. Some are not flat like the conifers, some are not above ground like the bulb scales and some lack major photosynthetic function like the spines. The leaves may have functions other than photosynthesis. Some leaves provide protection, support, storage and even acquisition of nitrogen.[1]
