Xylem is one of the two types of transport tissue in vascular plants (the other being phloem). The primary function of xylem is to transport water and some dissolved nutrients from the roots to the rest of the plant and also provides structural support.
Xylem tissue consists of tracheary elements (tracheids and vessel elements), which are dead cells that form continuous tubes for water transport, along with parenchyma cells, fibers, and sometimes sclereids. The movement of water in xylem is primarily driven by transpiration pull, evaporation of water from leaves.
