Answer 1

Explanation:

Starch test on leaves

When we put iodine on the leaves, one of them will turn blue-black and the other will be a reddish-brown. Iodine is an indicator that turns blue-black in the presence of starch. The leaf that was in the light turns blue-black, which demonstrates that the leaf has been performing photosynthesis and producing starch.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.,Hence to dissolve the chlorophyll or the green pigment present in the leaf we boil the leaf in alcohol when we are testing it for starch.
