Question

Which of the following elements of the phloem is responsible for conducting sugar?

• A. Companion cells
• B. Parenchyma cells
• C. Sieve tube
• D. None of the above

Answer 1

The correct option is C Sieve tube

• The sieve tubes are the conducting vessels in the phloem tissue.
• These are the long tube-like cells that have perforated transverse plates. These are the cells that are responsible for the conduction of food.
• The sugar is transported through the phloem vessels from the source end (leaves) to the sink end (roots).

Thus the correct answer is option C.
