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: -Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of “transport” tissues in plants-xylem and phloem. Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.
Detailed explanation-4: -The function of xylem is to transport water and nutrients from the roots to all parts of the body.
Detailed explanation-5: -Xylem transport water and minerals from roots to aerial parts of the plant. Phloem transport food and nutrients such as sugar and amino acids from leaves to storage organs and growing parts of the plant.
