प्रश्न
Will a leaf taken from a potted plant kept in a dark room for a few days turn blue black when tested for starch? Give reasons for your answer.
उत्तर
No, it will not turn blue black because all the starch stored in the leaf would have been used up by the plant and no starch would be synthesised in the leaves due to the non-availability of sunlight.
