What is the main function of xylem?

The main function of xylem is to transport water and minerals from the roots of the plant to the leaves and other parts of the plant. This process is crucial for plant survival, as water is necessary for various metabolic activities, including photosynthesis. The xylem vessels are structured to allow for the efficient movement of these essential components; they are made of tubular structures that facilitate the upward flow of water through capillary action and transpiration pull.

By delivering water and dissolved minerals, xylem plays a vital role in maintaining the plant’s turgidity, promoting growth, and supporting various physiological processes. In summary, the primary role of xylem is integral to the plant's ability to thrive by ensuring that it receives the necessary resources to function effectively.
