Solution
The correct option is A Half leaf experiment
The Moll’s half leaf experiment demonstrates the necessity of carbon dioxide in photosynthesis. The experiment involved the insertion of half part of a leaf inside a corked bottle containing KOH solution (absorbs CO2).
The bottle was kept outside in the sunlight for few hours. After that, the leaf was taken for a starch test. Part of the leaf that was inside the bottle gave a negative result for starch and the part outside showed a positive result. Thus, it was concluded that CO2 is necessary for photosynthesis.
