Question

The carbohydrates synthesized in the leaves are transported through sieve tubes most commonly in the from of:

• A. glucose
• B. starch
• C. sucrose
• D. cellulose

Answer 1

The correct option is C

sucrose

The correct answer is option C.

Explanation of the correct option:

1. Green plants synthesise sugars during the process of photosynthesis and the most commonly synthesised sugar is glucose.
2. Glucose is converted to sucrose for transportation all over the plant body.
3. The sucrose is transported through the sieve elements.

Explanation of the incorrect options:

Option A

Green plants synthesise sugars during the process of photosynthesis and the most commonly synthesised sugar is glucose.

Option B

Sucrose formed during translocation is converted into starch for long-term storage in roots, seeds and other vegetative parts.

Option D

Cellulose is present in the cell wall of plants it is not transported during translocation.

Final answer: The carbohydrates synthesised in the leaves are transported through sieve tubes most commonly in the form of sucrose.
