WebCharacteristics of Xylem. Xylem, one of the conducting tissues, is responsible for transferring nutrients and water from roots to the stem and leaves of the plant. It is composed of specialised cells called tracheary components that carry water. Tracheids are the first tracheary component discovered in the xylem. http://www.biology4kids.com/files/plants_xylemphloem.html
WebXylem is a specialised vascular tissue structure that, in addition to transporting water and inorganic ions, will also provide mechanical support to the plant. Together with phloem, they form a vascular bundle. Xylem is adapted to transport the sap, having no end walls, one-way flow system, non-living cells and narrow vessels. In addition to ... WebXylem and phloem are transport structures that together form a vascular bundle. Xylem carries water and dissolved minerals, starting at the roots (sink) and ending at the plant leaves (source). The movement of water is driven by transpiration in a unidirectional flow. Transpiration describes the loss of water vapour through the stomata.
