Explanation:

The leaf can be decolourised by boiling it and placing it in an alcohol bath.

It shows that white patches do not photosynthesize as iodine turns blue black in the presence of starch.

To decolourise a leaf we have to first take a beaker half-filled with water. Then we should boil it. After boiling the beaker we should add alcohol into it and then the leaf into it. Adding it the leaf decolourises itself.

Then we put the leaf out and add iodine solution in it which causes the leaf to turn blue black with a small region with white patch. The region with blue black colour contains chlorophyll while the rest doesnt.
