What is the primary function of xylem in plants?

The primary function of xylem in plants is to transport water and minerals from the roots upward to the leaves and other parts of the plant. This process is essential for the plant's survival, as it allows for photosynthesis to occur in the leaves, where sunlight is converted into energy. The xylem is made up of specialized cells that form hollow tubes, which facilitate the movement of water through capillary action and transpiration.

Additionally, xylem also contributes to the overall structural integrity of the plant, but its main role focuses on the upward transport of water and dissolved minerals necessary for growth and metabolic processes. Thus, while it provides some structural support, the primary function remains water and nutrient transportation.
