Detailed explanation-1: -The xylem and phloem are two conducting tissues present in plants. Xylem conducts minerals and water only in the upward direction i.e. from the roots towards the stem. The phloem transports food material from leaves to other parts of the plant body. It can conduct food in both directions.
Detailed explanation-2: -Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients.
Detailed explanation-3: -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. The process by which water evaporates from the leaves and draws more water from the roots is called ‘transpiration’.
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.
Detailed explanation-5: -The vascular tissue, phloem helps in the transportation of the synthesized food from the leaves to various storage organs.
