Explanation:
The process of photosynthesis can be represented by the following chemical equation;
6CO2 + 6H2O → C6H12O6 + 6O2.
So, if the carbon atom in CO2 is labelled with 13C, the 13C will appear in the glucose which is ultimately converted to carbohydrates- the energy molecules stored in plants. A typical example of a carbohydrate is starch.
