Question

will the test for starch work on a leaf taken from a plant that has been kept in the dark for a few days? Explain the reason for your answer. ​

Answer 1

Answer:

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
