Leaf \Leaf\ (l[=e]f), n.; pl. Leaves (l[=e]vz). [OE. leef, lef, leaf, AS. le['a]f; akin to S. l[=o]f, OFries. laf, D. loof foliage, G. laub, OHG. loub leaf, foliage, Icel. lauf, Sw. l["o]f, Dan. l["o]v, Goth. laufs; cf. Lith. lapas. Cf. Lodge.]
(Bot.) A colored, usually green, expansion growing from the side of a stem or rootstock, in which the sap for the use of the plant is elaborated under the influence of light; one of the parts of a plant which collectively constitute its foliage.
Note: Such leaves usually consist of a blade, or lamina, supported upon a leafstalk or petiole, which, continued through the blade as the midrib, gives off woody ribs and veins that support the cellular texture. The petiole has usually some sort of an appendage on each side of its base, which is called the stipule. The green parenchyma of the leaf is covered with a thin epiderm pierced with closable microscopic openings, known as stomata.
(Bot.) A special organ of vegetation in the form of a lateral outgrowth from the stem, whether appearing as a part of the foliage, or as a cotyledon, a scale, a bract, a spine, or a tendril.

Extended 15c. to very thin sheets of metal (especially gold). Meaning "hinged flap on the side of a table" is from 1550s.
"to turn over (the pages of a book)," 1660s, from leaf (n.). The notion of a book page also is in the phrase to turn over a (new) leaf (1570s). Related: Leafed; leaved; leafing.
n. The usually green and flat organ that represents the most prominent feature of most vegetative plants. vb. (context intransitive English) To produce leaves; put forth foliage.
Leaf is a Japanese visual novel studio under the publisher Aquaplus, and has offices in Yodogawa-ku, Osaka, and Tokyo. It and its competitor Key (to which it is often compared) are two of the most popular and successful dedicated visual novel studios operating today. It was launched out of obscurity by its early release To Heart. Leaf used the XviD video codec in several games: Aruru to Asobo!!, Tears to Tiara, Kusari, and ToHeart2 X Rated. Since XviD is free software, released under the GPL, Leaf was forced to release the source code to those games under the same license. One still required the game data to actually play the games with the source code. In addition, a free software engine called xlvns was developed soon after Leaf released its first three visual novels. Characters from Utawarerumono, Tears to Tiara, To Heart, and Kizuato are playable in Aquapazza: Aquaplus Dream Match, a fighting game developed by Aquaplus featuring characters from various Leaf games.
A leaf is an organ of a vascular plant.

Leaf was a Dutch band from Utrecht. Their first single, Wonderwoman was released in October 2007.
Leaf was founded in 2005 by a group of students from the Rockacademie. The band plays acoustic pop songs and had quite a bit of success at the Dutch Popronde 2006. In the spring of 2007 they came out on top in a talent contest held by the Dutch newspaper De Telegraaf. The band members are Annemarie Brohm, Tinus Konijnenburg, Ocker Gevaerts, Joni Scholten and Jeroen Blumers.
The band's independently produced album 'Life's a Beach' was received very well, and was later re-released on 16 November 2007 after securing a record label. One of the most popular singles on the album is Wonderwoman (a.k.a. "Why's my Life so Boring"), which went on to become a top 10 hit in the Dutch Top 40 charts. The song got an additional popularity boost due to it being used in the television show Koefnoen.
The band split up on 12 January 2009 due to creative differences within the group.
Leaf, previously a division of Scitex and later Kodak, is now a subsidiary of Phase One. Leaf manufactures high end digital backs for medium format and large format cameras. In 1991, Leaf introduced the first medium format digital camera back, the Leaf DCB1, nicknamed ‘The Brick’, which had a resolution of 4 million pixels (4 megapixels). As of 2012, Leaf produces the Credo line of digital camera backs, ranging from 40 to 80 megapixels. Until 2010, Leaf also produced photography workflow software Leaf Capture.
Typically a leaf is a thin, dorsiventrally flattened organ, borne above ground and specialized for photosynthesis. In most leaves, the primary photosynthetic tissue, the ( palisade mesophyll), is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of Eucalyptus palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves have distinctive upper (adaxial) and lower (abaxial) surfaces that differ in colour, hairiness, the number of stomata (pores that intake and output gases), epicuticular wax amount and structure and other features.
Broad, flat leaves with complex venation are known as megaphylls and the species that bear them, the majority, as broad-leaved or megaphyllous plants. In others, such as the clubmosses, with different evolutionary origins, the leaves are simple, with only a single vein and are known as microphylls.
Some leaves, such as bulb scales are not above ground, and in many aquatic species the leaves are submerged in water. Succulent plants often have thick juicy leaves, but some leaves are without major photosynthetic function and may be dead at maturity, as in some cataphylls, and spines). Furthermore, several kinds of leaf-like structures found in vascular plants are not totally homologous with them. Examples include flattened plant stems called phylloclades and cladodes, and flattened leaf stems called phyllodes which differ from leaves both in their structure and origin. Many structures of non-vascular plants, such as the phyllids of mosses and liverworts and even of some foliose lichens, which are not plants at all (in the sense of being members of the kingdom Plantae), look and function much like leaves.
