Phloem (/ ˈfloʊ.əm /, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to parts of the plant where needed. This transport process is called translocation.
Yet, despite this interest in xylem function, the relationship between xylem vulnerability and plant drought tolerance has only rarely been quantified (Brodribb & Cochard, 2009). As such, there is a significant gap between our knowledge of xylem cavitation and its application as an ecological tool.
The xylem tissue is adapted to its functions in different ways For instance the from O-LEVEL Biology at Beaconhouse School System. For more information regarding the structure and function of xylem and phloem, review the Irrigation and Rootstock sections. Leaves contain water which is Consequently, in the most common stain system, cellulose stains blue or green and lignin stains reddish or pink.) XYLEM. Xylem tissue functions in both water the xylem fibres disintegrate cellular contents at a slower pace, well before cell death.
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. Xylem fibres provide mechanical support and xylem parenchyma stores food materials and tannins and also conducts water radially.

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.
Xylem: Xylem transports water and solutes from the roots to the leaves. They are involved in the movement of water through a plant from its roots to its leaves.
the resulting embolisms can plug xylem vessels, making them non-functional. Xylem tissue has the dual functions of support and transport. It contains several different types of cells these are vessel elements, traceids, fibres and parenchyma Variation in xylem structure and function in stems and roots of trees to 20 m depth .

These systems use continuous tubes called xylem and phloem: - Xylem vessels carry water and minerals from the roots to the leaves Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage. The water‐conducting function of xylem is one of the major distinguishing features of vascular plants. Xylem parenchyma is an element of complex tissue called “Xylem”. Parenchyma cells of xylem are mainly involved in the storage of carbohydrate, fats and water conduction.

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.

Xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements. Learn more about xylem in this article.
