The figure shown below represents an activity to prove the requirements for photosynthesis. During this activity, two healthy potted plants were kept in the dark for 72 hours. After 72 hours, KOH is kept in the watch glass in setup X and not in setup Y. Both these setups are airtight and have been kept in light for 6 hours. Then, the Iodine test is performed with one leaf from each of the two plants X and Y.

This experimental setup is used to prove the essentiality of which of the following requirements of photosynthesis?
