why do we boil the leaf in alcohol when we are testing it for starch

We boil the leaf in alcohol when we are testing it for starch as this would remove the chlorophyll from the green leaf. 

Decolorised leaf is then treated with iodine and a blue black colour is obtained which confirms the presence of starch in the green portion of the leaf.
