Definitions:

Sapwood

The outer, younger part of a tree's trunk or branch that is active in transporting water and minerals from the roots to the leaves.

Secondary Xylem

Plant tissue that transports water and nutrients upwards from the roots; it also provides structural support and is a major component of wood.

Water Potential

Free energy of water; the water potential of pure water is zero and that of solutions is a negative value. Differences in water potential are used to predict the direction of water movement (always from a region of less negative water potential to a region of more negative water potential).

Functional Secondary Xylem

The mature, functional part of xylem that contributes to water and mineral conduction in plants, as well as structural support.
