Answer:
We boil the leaf in alcohol when we are checking it for starch to eradicate chlorophyll, which is the green pigment present in leaves. During the starch test, we observe the colour change of leaf from brown to blue when iodine is put on the leaf as iodine reacts with the starch present in the leaf.
