The right answer is tracheids allow for efficient transport of water over longer distances.

Tracheids are conduits for the transport of raw sap (composed of water and mineral salts) to vascular plants. They are composed of a series of elongated cells. During the formation of tracheids these cells die, are emptied of their contents and are fused vertically to form a hollow conduit. The tracheids are located in the xylem, plant tissue allowing the transport of raw sap. Derived from the primary xylem (protoxylème), they have a role in the overall support of the plant.

In addition to tracheids, angiosperms possess vessel elements for transporting raw sap.
