About Xylem
- Xylem transports water and minerals absorbed by the roots up to the leaves.
- Water is transported along the xylem by a process called transpiration.
- The xylem supports the stem of the plant making it harder to bend under its own weight.
- The xylem is formed when xylem cells create a chemical called lignin which builds up in a spiral shape around the cell wall. The xylem cells then die to leave behind hollow tubes supported by the spiral of lignin.
