Explanation:
When a leaf is exposed to sunlight, it undergoes photosynthesis, a process by which it produces glucose, a type of sugar, from carbon dioxide and water. Glucose is then converted into starch and is stored in the leaves. Iodine solution is used to test the presence of starch in leaves.
The experiment described in the question involves covering a leaf of a potted plant with a black cover and keeping it under sunlight for a few days. After that, the leaf is tested with iodine solution. If the colour of the covered leaf does not turn blue-black, it indicates that starch is not present in the leaf. There can be several reasons for this, but the most likely one is that the leaf did not receive enough sunlight during the experiment.
Photosynthesis occurs only in the presence of sunlight, and without it, the plant cannot produce glucose or starch. Therefore, if the leaf was covered with a black cover, it would not have received enough sunlight to produce starch. The absence of starch in the leaf is an indication that the leaf did not receive enough sunlight during the experiment.
Conclusion:
The correct answer is option D, which states that starch is prepared only in the presence of sunlight.
