Question

what are the colors of the green & non-green portions of a decolourised variegated leaf when treated with iodine solution in the experiment for testing the necessity of chlorophyll for photosynthesis and why?​

Answer 1

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.)

Answer 2

Answer:

leaves( green ) contain starch gives blue black colour with iodine and that leaves ( non green)

which doesn't contains starch don't show blue black colour.
