Sap is a fluid transported in xylem cells (tracheids or vessel elements) or phloem sieve tube elements of a plant. FLUID ( F ast L ight '''U'''ser '''I'''nterface D esigner is a graphical editor that is used to produce FLTK Source code In Vascular plants xylem is one of the two types of transport tissue Phloem being the other In Vascular plants phloem is the living tissue that carries organic Nutrients (known as photosynthate particularly Sucrose, a sugar to Plants are living Organisms belonging to the kingdom Plantae. Fluid found in the vacuole of other cells is sometimes referred to as "cell sap". Other liquid compounds found in plants or exuded by plants, such as latex, resins, and mucilage are sometimes incorrectly referred to as sap.

Mucilage is a gooey polar Glycoprotein; an exopolysaccharide; a Polymer produced by most plants and some microorganisms

Xylem sap consists primarily of water, with hormones, mineral elements, and other nutrients dissolved in the sap. Transport of sap in xylem is generally "basipetal", or upward from the roots toward the leaves. Over the past century, there has been some controversy regarding the mechanism of xylem sap transport, although most plant scientists today agree that the bulk of the evidence supports the cohesion-tension theory of xylem sap transport. Transpirational pull is the main phenomenon driving the flow of Water in the Xylem tissues of large Plants Mechanisms Transpirational pull Phloem sap consists primarily of water, with sugars, hormones, and mineral elements dissolved in the sap. Phloem sap transport occurs from sources (a location where carbohydrates are produced or stored) toward sinks (a location where carbohydrates are utilized). The pressure flow hypothesis proposes a mechanism for phloem sap transport. The Pressure Flow Hypothesis is the best-supported theory to explain the movement of food through the phloem

Maple syrup is made from reduced maple tree xylem sap. Maple syrup is a sweetener made from the sap of Maple trees In Canada and the United States it is most often eaten with waffles and pancakes Acer ( maple) is a Genus of Trees or Shrubs They are variously classified in a family of their own the Aceraceae, or A tree is a perennial Woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or In Vascular plants xylem is one of the two types of transport tissue Phloem being the other In some countries (e. g. , Russia or Latvia) it is common to collect the early spring sap of birch trees (so called "birch juice") for human consumption; the sap can be used fresh or fermented. Russia (Россия Rossiya) or the Russian Federation ( Rossiyskaya Federatsiya) is a transcontinental Country extending Latvia ( Latvija officially the Republic of Latvia (Latvijas Republika is a Country in Northern Europe in the Baltic region. Birch is the name of any Tree of the genus Betula ( Bé-tu-la) in the family Betulaceae, closely related to the "Birch juice" is slightly sweet and very refreshing, but tends to become bitter in late spring; the rule of thumb is to collect it before any green leaves have appeared.
