So, if xylem tissues are destroyed, most likely the branch of the tree will not survive due to lack of water. If the xylem vessels are plugged or xylem is removed from a plant, then the leaves would first get wilted as they will not get any water and finally the plant would die. This is known as transpiration. And more than 50 percent of a tree is made up of — you guessed it — water!
Leaves are the most photographed aspect of a tree or forest. Yet the most important part of the tree is the part not seen, the roots. Roots provide the necessary nutrients for the tree itself, without which, the tree would not get nourishment or water. The tree depends on the roots for feeding it and making it grow.

In this sense, xylem are completely unlike the circulatory system. Even the sap that flows in a tree has no transport cells like red blood cells and white blood cells; it is a fluid containing loose sugars and nutrients.
Xylem tissue forms from cells that are derived from meristematic cells commonly called procambium and cambium. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients. In stems and roots, the xylem typically lies closer to the interior of the stem with phloem towards the exterior of the stem.
In the stems of some Asterales dicots, there may be phloem located inwardly from the xylem as well. Between the xylem and phloem is a meristem called the vascular cambium. Xylem consists of dead cells. The cells that make up the xylem are adapted to their function: They lose their end walls so the xylem forms a continuous, hollow tube.
Unlike xylem which is composed primarily of dead cells , the phloem is composed of still-living cells that transport sap. The sap is a water-based solution, but rich in sugars made by photosynthesis. In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels. Lignin gives strength and support to the plant.
We call lignified cells wood. In the non-living world, elements are found in different proportions, and some elements common to living organisms are relatively rare on the earth as a whole, as shown in Table 1. Oganesson is a synthetic chemical element with symbol Og and atomic number Oganesson is believed to exist in form of solid. Note that most living matter consists primarily of the so-called bulk elements: oxygen, carbon, hydrogen, nitrogen, and sulfur—the building blocks of the compounds that constitute our organs and muscles….
Classification of the Essential Elements. Scientists believe that about 25 of the known elements are essential to life. Nonetheless, all organisms are built from the same six essential elemental ingredients: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur CHNOPS.
The most important function of hydrogen in the human body is to keep you hydrated.
