Expert Answer
Rinsing off the leaf in iodine solution turns the leaf colour blue-black colour which proves that there is the presence of starch. So, after the starch test, the green region of the leaf turns blue-black, while the non-green part of the leaf stains brown in colour.Only the green region of the leaf manufactures the starch. This proves that chlorophyll is necessary for photosynthesis.
