Answer:
In the experiment, light is essential for photosynthesis, the uncovered region of the leaf, receives sunlight and performs photosynthesis. The leaf, therefore turns blue-black after putting iodine in this area due to the production of starch. Dilute iodine solution is originally light yellowish in colour and it gives a blue-black color when in contact with another substance indicating the presence of starch in that substance.
