What vascular tissue transports water and dissolved essential minerals within a tree?

• A. Parenchyma
• B. Xylem
• C. Phloem
• D. Cambium

Answer: (B)

The vascular tissue responsible for transporting water and dissolved essential minerals within a tree is xylem. Xylem consists of specialized cells that allow for the efficient movement of water from the roots, where it is absorbed from the soil, upward through the stem and into the leaves. This upward movement, known as transpiration pull, is crucial for maintaining the plant's hydration and facilitating essential physiological processes, including photosynthesis. In addition to water transport, xylem also plays a significant role in providing structural support to the tree, enabling it to grow tall and withstand various environmental stresses. Understanding the role of xylem is vital in arboriculture, as ensuring the health of xylem can impact the overall vitality of the tree. The other types of vascular tissues, such as phloem, primarily transport sugars and other metabolic products downward from the leaves, while cambium is involved in growth and generation of new xylem and phloem tissues. Parenchyma cells have various functions, including storage, but they do not play a direct role in the transport of water and minerals.
