Hey dear!
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. So if there was place of photosynthesis, there was no formation of starch.
Hence, the leaf would not turn blue-black as there is absence of starch.
