The radio-labelled carbon in carbon dioxide supplied to potato plants in an experiment was seen in the tuber eventually. Trace the movement of the labelled carbon dioxide.

To observe the creation of Carbohydrates and the following movement of starch from various parts of the plant to the others, the radiolabelled carbon dioxide is supplied. Photosynthesis occurs in the leaves. The radioactive carbon dioxide will travel to the leaf parenchyma. Following the process of photosynthesis, the radioactive carbon will be the Carbohydrate in the leaves. This can also be proved by the presence of starch which is a by-product of photosynthesis. The carbohydrates soon transform into starch and are moved to the other organs to store it. Thus the radioactive carbon can be detected in the tubers, as the starch is stored in tubers.
