xylem parenchyma
parenchyma
xylem vessels

Solution
xylem vessels
Xylem (a complex permanent tissue) is the chief conducting tissue of vascular plants responsible for the conduction of water and inorganic solutes. The tissue is composed of four kinds of cells: tracheids, vessels (or tracheae), xylem parenchyma, and xylem fibers. Vessels and tracheids help in the long-distance vertical conduction of water and minerals from the roots to different parts of the shoot system. The main stem along with all of its branches are all supplied with water and mineral by mean of xylem vessels and tracheids. Radial conduction i.e., sideways conduction of water occurs by xylem parenchyma.
