What is the primary role of xylem in plants?

The primary role of xylem in plants is to transport water. Xylem cells are specialized for conducting water and dissolved minerals absorbed from the soil upwards through the plant. This movement is essential for various physiological processes, including photosynthesis, nutrient transport, and maintaining turgor pressure in cells, which helps to keep the plant upright and healthy.

While xylem also contributes to the structural support of plants due to its lignified walls, its main function revolves around the transport of water and minerals rather than providing food or engaging directly in photosynthesis. Other plant tissues, such as phloem, are responsible for transporting the food produced during photosynthesis.
