Maple Sap
Maple syrup is a syrup made from the sap of maple trees. In cold climates, these trees store starch in their trunks and roots before winter; the starch is then converted to sugar that rises in the sap in late winter and early spring. Maple trees are tapped by drilling holes into their trunks and collecting the sap, which is processed by heating to evaporate much of the water, leaving the concentrated syrup. Maple syrup was first made by the Indigenous peoples of North America. The practice was adopted by European settlers, who gradually changed production methods. Technological improvements in the 1970s further refined syrup processing. Virtually all of the world's maple syrup is produced in Canada and the United States. The Canadian province of Quebec is the largest producer, responsible for 70 percent of the world's output; Canadian exports of maple syrup in 2016 were C$487 million (about US$360 million), with Quebec accounting for some 90 percent of this total.

Xylem
Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients. The word ''xylem'' is derived from the Ancient Greek word (''xylon''), meaning "wood"; the best-known xylem tissue is wood, though it is found throughout a plant. The term was introduced by Carl Nägeli in 1858. Structure The most distinctive xylem cells are the long tracheary elements that transport water. Tracheids and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called ''vessels''. Xylem also contains two other type of cells: parenchyma and fibers. Xylem can be found: * in vascular bundles, present in non-woody plants and non-woody parts of woody plants * in secondary xylem, laid down by a meristem called the vascular cambium in woody plants * as part of a stelar arrangement n ...

Waffle
A waffle is a dish made from leavened batter or dough that is cooked between two plates that are patterned to give a characteristic size, shape, and surface impression. There are many variations based on the type of waffle iron and recipe used. Waffles are eaten throughout the world, particularly in Belgium, which has over a dozen regional varieties. Waffles may be made fresh or simply heated after having been commercially cooked and frozen. Etymology The word ''waffle'' first appears in the English language in 1725: "Waffles. Take flower, cream..." It is directly derived from the Dutch , which itself derives from the Middle Dutch . While the Middle Dutch is first attested to at the end of the 13th century, it is preceded by the French in 1185; both from Frankish 'honeycomb' or 'cake'. Other spellings throughout modern and medieval Europe include waffe, wafre, wafer, wâfel, waufre, iauffe, gaufre, goffre, gauffre, wafe, waffel, wåfe, wāfel, wafe, vaffel, and våff ...

It is native to western North America, mostly near the Pacific coast, from southernmost Alaska to southern California. Some stands are also found inland in the foothills of the Sierra Nevada of central California, and a tiny population occurs in central Idaho. Description Bigleaf maple can grow up to tall, but more commonly reaches tall and . The species' current national champion for size is located in Lane County, Oregon.

Acer Saccharinum
''Acer saccharinum'', commonly known as silver maple, creek maple, silverleaf maple, soft maple, large maple, water maple, swamp maple, or white maple, is a species of maple native to the eastern and central United States and southeastern Canada. It is one of the most common trees in the United States. Although the silver maple's Latin name is similar, it should not be confused with '' Acer saccharum'', the sugar maple. Some of the common names are also applied to other maples, especially ''Acer rubrum''. Description The silver maple tree is a relatively fast-growing deciduous tree, commonly reaching a height of , exceptionally . Its spread will generally be wide. A 10-year-old sapling will stand about tall. It is often found along waterways and in wetlands, leading to the colloquial name "water maple". It is a highly adaptable tree, although it has higher sunlight requirements than other maple trees. The leaves are simple and palmately veined, long and broad, with deep ...
