Answer 2

The translocation of food and other substances takes place in the sieve tubes with the help of adjacent companion cells both in upward and downward directions.

• Translocation refers to the process of bulk distribution of food in plants over long distances. Phloem, vascular tissue, is responsible for the transportation of food from leaves to other parts of the plant.
• The sieve tubes possess pores and are interconnected to form a long network throughout the body of the plant. Translocation of food takes place in these tubes.
• Sieve tubes are always found in association with companion cells. They are nucleated and are responsible for maintaining the flow of substances in sieve tubes in both upward and downward directions.
