Which tissue in plants contains lignin as a major component of its cell wall?

Lignin is an essential component of the cell wall in xylem tissue in plants. Xylem tissue is responsible for transporting water and minerals from the roots to the rest of the plant. It is composed of several types of specialized cells including tracheids, vessels, xylem parenchyma, and xylem fibres. Lignin provides strength and support to the xylem cell walls, allowing them to withstand the pressure generated by water transport.
