It should be understood that Iodine solution is used to test leaves for the presence of starch. This will show a blue-black color, which means the presence of starch.
This process can simply be demonstrated by simply following these steps.
* Take two potted plants of the same kind.
* Keep one in the dark (or in a black box) for 72 hours and the other in the sunlight.
* Take one leaf from each of the plants.
* Put few drops of iodine solution on each of the leaves.
