Question

we keep a healthy potted plant in a dark room for some days to ................ the leaves​

Answer 1

No, a leaf plucked from a potted plant kept in a dark room for a few days, will not turn blue black when tested for starch. 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. And starch is the product of photosynthesis.
