Besides transporting water, what is another role of xylem in plants?

• A. Storing sugars.
• B. Providing structural support.
• C. Carrying out photosynthesis.
• D. Absorbing nutrients from the soil.

Answer: (B)

Xylem not only moves water and minerals through the plant, it also provides structural support. The cells in xylem develop thick, lignified secondary walls and often die at maturity, forming a rigid, woody tissue. Those lignified fibers and vessel elements create a strong backbone that helps stems, trunks, and branches stay upright and resist bending or breaking from wind and gravity. That sturdy, wood-like tissue is why woody plants can grow tall and maintain their shape.

Storing sugars is mainly a function associated with phloem and storage parenchyma, not xylem. Photosynthesis happens in the chloroplasts of leaf cells, not in xylem. Absorbing nutrients from the soil is carried out by roots and absorbed nutrients are then transported by xylem, but the act of absorption itself isn’t a role of xylem.
