प्रश्न
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.
उत्तर
To observe the following movement of starch and the creation of carbohydrates from various parts of the plant to the others, the radiolabeled carbon dioxide is supplied. Leaves perform photosynthesis; the radioactive carbon dioxide is received by the leaves.
Following the photosynthesis process, carbohydrates in the leaves are the radioactive carbon. The presence of starch which is the by-product of photosynthesis is also proved. The carbohydrates transform into starch and are moved to the other organs to store. Hence, in the tubers, there are radioactive carbons, such as starch present in tubers.
