What is the role of xylem in plants?

Xylem plays a crucial role in the plant's vascular system, primarily being responsible for the transport of water and dissolved minerals from the roots upward through the stem to the leaves and other parts of the plant. This upward movement of water is essential for various physiological processes, including photosynthesis, nutrient transport, and temperature regulation.

In addition to transporting water, xylem is crucial for maintaining the structural integrity of the plant, as it helps support the plant against gravity and environmental conditions. The arrangement of xylem vessels, which can vary among different plant species, facilitates efficient water transport, allowing plants to thrive in diverse environments. Thus, its primary function focuses on the essential movement of water, which is vital for the plant's survival and growth.
