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: -The transport in xylem in usually unidirectional, whereas in phloem it is bidirectional.

Detailed explanation-3: -Phloem transport is bidirectional because sucrose gets accumulated in the phloem tissue and absorbs water creating a high turgor pressure. Other areas have low turgor pressure due to loss of water.

Detailed explanation-4: -Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose(sugar) and amino acids between the leaves and other parts of the plants.
