Detailed explanation-1: -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-2: -The upward movement of sap containing water and dissolved minerals from the root cells to xylem is called the ascent of sap.

Detailed explanation-3: -Final answer: Xylem conducting tissue transports water and minerals from roots upwards towards the leaves.

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.

Detailed explanation-5: -The movement of water in the xylem is unidirectional and is always upward. The upward movement of water is due to pressure created by transpiration, i.e. transpiration pull.
