What is the primary role of the xylem in vascular plants?

The primary role of the xylem in vascular plants is to transport water from the roots to the leaves and other parts of the plant. This process is crucial for several reasons: it enables photosynthesis by supplying water to the leaves, helps maintain turgor pressure in plant cells, and assists in the transport of nutrients dissolved in the water. The xylem is specialized for this function, composed of vessel elements and tracheids that facilitate the efficient movement of water due to their hollow structure.

While other structures within a plant serve different functions, such as transporting minerals or providing structural support, the xylem is specifically adapted for the movement of water, making this its primary role.
