Question

The tissue responsible for translocation of food material is

• A. Parenchyma
• B. Sieve tubes
• C. Vessels
• D. Fibres

Answer 1

The correct option is B Sieve tubes

Phloem is a heterogeneous tissue made up of phloem parenchyma, sieve tubes, companion cells and phloem fibers. Sieve tube elements are the tubular structure which is joined end to end. The main function of the sieve tube is the transport of carbohydrates, primarily sucrose, in the plant.
Vessels and fibers involve in the transport of water and minerals. Parenchyma makes up the soft tissue of plants and does not involve in transportation

So, the correct answer is 'Sieve tubes'
