Question: Explain two ways in which the xylem tissue is adapted for transporting water?
Xylem tissue is uniquely adapted for efficient water transport in plants. One key adaptation is the structure of xylem cells, which form long tubes that are dead at maturity, allowing for uninterrupted water flow. These cells lose their end walls, creating a continuous, hollow column for water to ascend from roots to leaves. Additionally, the walls of xylem cells are reinforced with lignin, a compound that strengthens the cells and prevents them from collapsing under the pressure of water transport. This lignification also helps to maintain the integrity of the water column against the forces of tension generated during transpiration. Together, these adaptations enable the xylem to transport water effectively against gravity, contributing to the plant's overall ability to thrive in various environments.
