Sapwood is the outer part of the tree that performs which function?

Explanation:
Sapwood is the active xylem in the outer wood that moves water and minerals from the roots up to the leaves. It can also store some carbohydrates as a food reserve. This practical function—conducting sap while also providing storage in the living, outer wood layer—is why the description fits sapwood best. The inner heartwood mainly stores resins and other compounds and is less conductive; the cambium is the growth layer that makes new xylem and phloem, and the bark is the protective outer covering.
