we take a potted plant like Croton whose leaves are partially green and partially white the green part of the leaf has chlorophyll but the white part of the leaf does not have chlorophyll
place this plant in the complete dark place for about 3 to 4 days into discharge its leaves.
take out the potted plant from the dark place and keep it in a bright sun sign for 3 to 4 days.
pluck the very a gated leaf from the plant boil it in the water for a few minutes and then remove it's a green colour chlorophyll by boiling it in alcohol the green part of the leaf a gets decolourise so we get decolourised leave.
was the decolorize leaf with hot water to soft and 18 and remove any chlorophyll which may be sticking on it
poor iodine solution over the colorless leaf and observe the change of colour of the leave.
we will find that the outer part of the leaf that was originally white without chlorophyll does not turns blue black and adding iodine solution showing that no starch is present in this outer part of the leaf from this observation we conclude that the photosynthesis to make starch does not take place without chlorophyll.
