Xylem is a type of tissue found in vascular plants that is responsible for transporting water and dissolved minerals from the roots to the rest of the plant. It consists of various cell types, including tracheids and vessel elements, which work together to facilitate this movement. The structure of xylem allows for efficient water transport, essential for plant growth and survival. In addition to its role in water transport, xylem also provides structural support to the plant. The cells in xylem are often lignified, meaning they have a tough, woody texture that helps strengthen the plant's overall structure. This support is crucial for plants like trees that grow tall and need stability.
