Question

The downward conduction of sugars from the leaves is carried out by

• A. Xylem
• B. Phloem
• C. Cambium
• D. Bark
• E. Pith

Answer 1

Answer: (B)

Phloem

Leaves have the raw material to produce food, the sugars. This food is translocated from leaves to all the parts of the plant's roots and stems for storage and utilization. Phloem tissue is responsible for translocating food to all parts of the plant. Phloem consists of cylindrical cells called sieve tubes which help in carrying out translocation of sugars. Although, this translocation of sugars occurs at the expense of energy. So, the correct answer is option B.
