Answer:
Xylem is a complex permanent tissue, which is specialized for the conduction of water and mineral substances in the plant body. Xylem is a heterogenous tissue made up of four different types of cellular elements. They are xylem tracheids, xylem tracheae, xylem fibers and xylem parenchyma. Of these, the tracheids and the tracheae are described as essential elements since they are directly involved in the translocation of water and mineral substances. Xylem fibers and xylem parenchyma are described as associated elements, since they are only supporting structures. The tracheids, the trachea and the xylem fibers are non-living components, while xylem parenchyma represents the only living component of the tissue.
Therefore, the correct answer is option A.
