Detailed explanation-1: -In plants, water and minerals are transported through xylem cells from soil to the leaves. The xylem cells of roots, stems and leaves are interconnected to form a conducting channel that reaches all parts of the plant body. The root cells take ions from the soil.

Detailed explanation-2: -Abstract. 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: -Main function of xylem – upwards water transport. The xylem, vessels and tracheids of the roots, stems and leaves are interconnected to form a continuous system of water-conducting channels reaching all parts of the plants. The system transports water and soluble mineral nutrients from the roots throughout the plant.

Detailed explanation-4: -The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots. Xylem cells constitute the major part of a mature woody stem or root.
