Explanation:
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: -These compounds are transported by the phloem tissue, which allows them to go both up and down within the plant, unlike sap which moves through the xylem.
Detailed explanation-3: -Hence, the movement of food through the phloem is bi-directional i.e. both in upward and downward directions. The process of food transportation via the phloem requires ATP.
