Xylem is also called which term?

• A. Heartwood
• B. Sapwood
• C. Phloem
• D. Ray

Answer: (B)

Xylem is the tissue that moves water and minerals from the roots upward in a plant. In wood, the part that is actively conducting water is the outer, younger portion called sapwood. As the tree ages and the xylem becomes darker and more filled with secondary compounds, it turns into heartwood, which no longer conducts water but provides structural support. Phloem is a separate tissue that transports sugars, not water, and rays are radial sheets of cells within the wood that aid storage and lateral transport, not the main water-conducting tissue. So the term that refers to the water-conducting part of xylem is sapwood.
