Answer:
A star-shaped figure was cut in the black paper strip used for covering the leaf of a destarched plant. It was used for demonstrating that light is necessary for photosynthesis. At the end of the experiment when the leaf was tested for starch with iodine, the star-shaped figure on the leaf was found to be blue black in colour. It was exposed to light and hence, starch was formed in this part of the leaf.
