Lignin is present in the xylem to provide structural support and to help water-proof the cell walls, allowing them to withstand the high pressure generated as water is transported upward through the xylem vessels. This polymer strengthens the cell walls, preventing collapse and ensuring the stability of the xylem tissue, which is crucial for the efficient transport of water and minerals from the roots to the rest of the plant. Additionally, lignin also contributes to the overall rigidity and mechanical strength of the plant, providing support for its upright growth.
