Answer: The change of color into blue or black indicates the presence of starch in the leaf.
Explanation: The iodine solution test is an indicator test for the presence of the starch material in leaves. Plants produce their food by the process of photosynthesis. Conversion of green leaf into blue or black color says that starch is present in the plants, a form of energy.
Hence, the final answer is starch.
