Error propagation (or uncertainty propagation) is defined as the effect of varying uncertainty on a function.
It is a calculus-based statistical calculation designed to combine the uncertainties of multiple variables to provide an accurate measure of uncertainty.
Every measurement has an element of uncertainty, and not all uncertainties are created equal. Therefore, the ability to properly combine the uncertainties of different measurements is crucial.
The uncertainty in the measurement arises from a number of reasons: instrument variability, different observers, differences between samples, time of day, etc. Typically, the error is expressed as the standard deviation (σx ) size.

The sinks are the areas where growth is occurring right now and the storage areas. These components of the sinks include the roots, the flowers, and the fruits. The roots may convert some sucrose to starch and store it.
The flowers use the sucrose to create fructose and later when the fruits are developing, quite significant amounts of sucrose may be used to produce sweet fruit ready to draw in animals.
However, there is a time of year when many plants go dormant. They wait out the harsh conditions during this phase while engaging in less activity. While dormant, plants rely on their reserves of starch, oils, and other materials to survive instead of photosynthesis. They resume growing when the seasons change. Now, sucrose is created from the materials that were previously stored, and it is shipped to the growing area.
