Question

Which of the following isotopes would be useful in finding the path of translocation of food?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

'Translocation of food' basically means transport of organic solutes especially sugars such as glucose, and other organic molecules. This takes place primarily through the phloem. These organic molecules can be tracked using the Carbon-14 isotope $C^{14}$.
