Detailed explanation-1: -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.
Detailed explanation-2: -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-3: -Both lignin and cellulose are found in the rigid cell walls of the xylem cells (those that conduct water) in the primitive plant Selaginella.
Detailed explanation-4: -What is the main function of xylem? 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-5: -The correct answer is Transport of water from roots to leaves.
