Expert Answer
(a) Leaf is covered with black strip so that some part of the leaf does not receive sunlight.
(b) Aim of this experiment is to show that sunlight is necessary for photosynthesis.
(c) Yes, destarching of leaf is necessary before performing this experiment. During this period, all the starch from leaves will be removed to the storage organs and the leaves will not show the presence of starch. This ensures that any starch present after the experiment has been formed under experimental conditions.
