Xylem
Tracheids and vessel elements
In vascular plants, the xylem is the tissue that carries water up the root and stem.

Xylem makes up the wood region. The xylem vessels made in the spring, when water is plentiful, have larger diameters than those made later in the season. No xylem is made during the dormant season.
