Answer:
The green part will turn blue black when iodine was added while the part which was not green did not show any change.
It is because the green part contained chlorophyll in it. Therefore starch was present in that part of leaf.
(Iodine is used for the presence of starch. It turns the medium containing starch blue black.)
