Detailed explanation-1: -Complete answer: The storage of metabolic products is not a function of xylem.
Detailed explanation-2: -Water and sugars are transported by xylem vessels and phloem tubes, respectively. Since these two conduits are hydraulically connected, it can be expected that both transport processes are physiologically coupled.
Detailed explanation-3: -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-4: -Xylem does not help in the transport of photo sent its or sugars. Instead, it helps only in the transport of water and minerals. Therefore, the first statement is not true.
Detailed explanation-5: -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.
