Question

Transport of food material in plants takes place through:

• A. Companion cells
• B. Sieve Tubes
• C. Tracheids
• D. Xylem

Answer 1

The correct option is B Sieve Tubes

• The transport of soluble products of photosynthesis is called translocation and it occurs in the part of the vascular tissue known as phloem.
• Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells.
• Sieve tubes: Transport sugars and nutrients up and down the plants in sieve cells.
• Companion cells: Controls the activity of the sieve tube.
• Phloem parenchyma: Provides mechanical strength to the plant.
• Phloem fibres: Stores compounds such as starch.

So, the correct answer is option B.
