It is used to demonstrate the importance of chlorophyll in photosynthesis. Plant with variegated leaves is de starched and then placed in the sunlight for a few hours, then the iodine test for starch is carried out. The green parts of the leaves will test positive for starch and therefore turn blue black. The non-green parts did not photosynthesize die to absence of chlorophyll and iodine color will remain brown.
