Which of the following best describes the role of xylem in a plant?

The role of xylem in a plant is primarily to transport water and minerals from the roots to other parts of the plant. Xylem consists of specialized cells that allow for the efficient movement of water, which is essential for various physiological processes including photosynthesis, nutrient transport, and thermoregulation. As water is absorbed by the roots, it travels upward through the xylem vessels, engaging in a process driven by evaporation of water from the leaves (transpiration), creating a negative pressure that facilitates this upward movement.

While xylem does contribute to the structural support of the plant, which is a crucial function, its primary role is specifically linked to the transport of water and minerals. This distinction is important, as other tissues—like phloem—are responsible for transporting sugars and nutrients produced during photosynthesis, illustrating the specialized roles that different plant tissues play in overall plant health and function.
