Xylem cells are elongated cells with lignified secondary thickening of the cell walls.

The possession of xylem defines the vascular plants or Tracheophytes.
1 Sclerenchyma tissues are thick-walled support cells found throughout the plant as fiber. 2  Xylem is a structurally complex tissue that conducts water and nutrients from the roots to all parts of the plant. 3  The xylem is comprised of a series of long tubes made up of shorter vessel members.n reviewing plant physiology, plant cells are grouped into tissues based on similar characteristics, then into five distinct structures (organs). 1  Cells â individual building blocks for life processes and growth.
