You can perform an experiment to show that chlorophyll is necessary by using a a potted plant having variegated leaves.(This ia a leaf having several different colours) Destarch the plant by keeping it in the dark for several days. During this time, no more starch is made and the starch present is used up in respiration. The plant is then placed in strong sulinght fo a few hours. Remove one leaf and test for starch with iodine solution. You will notice that the non-green parts of the leaf turns reddish brown due to the absence of starch. However, the green parts of the leaf turns blue black confirming the presence of starch. Hence, it is demonstrated that chlorophyll is needed in plants.
