The xylem tissue primarily transports water throughout the plant. It plays a crucial role in the plant's ability to absorb water from the soil and transport it upwards from the roots to the leaves and other parts of the plant. This process, known as transpiration, helps in maintaining the plant's structure and facilitating essential biological processes such as photosynthesis, where leaves require water to produce glucose.

Additionally, while the xylem does also transport dissolved minerals, its primary function is the movement of water. This differentiation is essential in understanding how nutrients and water are distributed within plants, as other tissues, such as phloem, are responsible for transporting sugars like glucose and amino acids.
