Xylem is a type of tissue in vascular plants that transports water and some nutrients from the roots Function of Xylem. The main function of xylem is to transport water, and some soluble nutrients including minerals and Structure of Xylem. Xylem is made up of several Xylem är en ledande och mekaniskt stödjande vävnad i kärlväxter. (Mossor har alltså inget xylem.) Det transporterar vatten och mineraler från rötterna och vidare ut i plantan, samt har en stödjande funktion. Xylemet utgörs av en blandning av döda och levande celler som är lignifierade.

Elements of xylem • 1)Tracheary elements These are nonliving cells, provide support and conduct water. Xylem parenchyma may function as a storage tissue, the cells becoming blocked with starch (as in ipecacuanha). The xylem parenchyma cells may grow into the vessel cavities and form tyloses which block up the vessel and render it non-functional, a process which occurs in the development of heartwood ( Fig. 42.6P ). 2020-07-26 · The xylem is a tissue which transports water and minerals from the roots up the plant stem and into the leaves. Xylem consists of dead cells.

In order for a xylem to carry out its functions successfully and efficiently, it must have to be adapted. One of the main adaptations of the xylem is the ring of lignin that forms a spiral pattern The main function of the xylem is water transport from roots to the other parts of the plant. Xylem also provides mechanical strength. Tracheids and vessels are the main elements for conducting water.
