Detailed explanation-1: -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.
Detailed explanation-2: -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.
Detailed explanation-3: -The xylem is a type of tissue in vascular plants that transfers water. Water and soluble nutrients such as minerals and inorganic ions are transported from the roots to the rest of the plant by the xylem. Tracheary elements, which are specialized water-conducting cells, make up xylem tissue.
Detailed explanation-4: -As transpiration occurs, it deepens the meniscus of water in the leaf, creating negative pressure (also called tension or suction). The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw.
Detailed explanation-5: -The xylem is a tissue which transports water and minerals from the roots up the plant stem and into the leaves.
