Expert Answer
Yes, there will be difference in results of two experiments.This is because, since it was kept in a dark room where there was no sunlight, the plant was unable to prepare the food by photosynthesis. An whne kept in sunlight, the plants prepare food which results in leaf turning blue-black as there is presence of starch.
