The tissue of vascular plants that conducts water and minerals, provides support, and consists of tracheary elements and parenchyma cells. Woody tissue is made of secondary xylem produced by the vascular cambium.

xylem
Xylem cells in the stem carry water from a plant's roots to its leaves. The phloem distributes food that is made in the plant's leaves to other parts of the plant. The cambium cells divide into either xylem or phloem cells. The cortex and pith, seen in the stem cross section, provide structural support.

xy·lem

(zī′ləm)
A tissue in vascular plants that carries water and dissolved minerals up from the roots through the stem to the leaves and provides support for the softer tissues. Xylem consists of various elongated cells that function as tubes. In a tree trunk, the innermost part of the wood is dead but structurally strong xylem, while the outer part consists of living xylem, and beyond it, layers of cambium and phloem. See more at cambium, photosynthesis. Compare phloem.

xylem

Tissue in plants that carries water and mineral salts from the roots to the rest of the plant.
