Sap

Definition - What does Sap mean?

Sap is a fluid transported throughout a plant via xylem cells or its phloem sieve tube elements. Sap carries water and nutrients from the roots and disperses them to the leaves and stems. Sap should not to mistaken as resin or latex, as those are separate elements with separate functions.

MaximumYield explains Sap

Sap is the life-blood of a plant and is how its leaves and stems receive the nutrients it needs to carry out the photosynthesis process. It also helps disperses moisture throughout the plant.

Xylem sap consists mostly of water, while phloem sap consists primarily of sugars, minerals, fats, hormones, and certain elements and trace elements dissolved in water. Some trees are higher in phloem sap and sugar content than others.

Throughout the ages, the sap of some trees, most notably red maple, has been harvested by humans who later boil it down to make a sugary syrup or brown sugar.
