What does it mean to impregnate xylem a cell wall?

The walls of xylem cells are lignified (strengthened with a substance called lignin). This allows the xylem to withstand pressure changes as water moves through the plant.

Explanation:

The xylem transports water and minerals from the roots up the plant stem and into the leaves.

In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels.

Vessels:

Lose their end walls so the xylem forms a continuous, hollow tube. Become strengthened by a chemical called lignin. The cells are no longer alive. Lignin gives strength and support to the plant. We call lignified cells wood. Transport in the xylem is a physical process. It does not require energy.
