noun, plural: xylem fibers
The xylem is the vascular tissue responsible for the upward conduction of water and nutrients from the roots. The xylem tissue moves water and nutrients to various parts of the plant such as shoots and leaves. Its major components include xylem parenchyma, xylem fibers, tracheids, and xylem vessels.
The xylem fibers are non-living sclerenchyma cells as they lose their protoplast at maturity. These cells are found in between the tracheids and xylem vessels of the xylem tissue. Sclerenchyma cells are narrow and elongated cells with tapering ends. They are former parenchyma cells that developed secondary cell walls. Their cell walls become lignified. Their elasticity and great tensile strength make them an essential component in the xylem as they protect and provide mechanical support to the major water conducting tissues of the xylem.
