Answer 1

Answer:

from bijus

Explanation:

Immerse the leaf in boiling alcohol to decolourize it. Leaf slowly loses its green color, which goes into the alcohol. Dip this decolorized leaf in iodine solution. Now remove the leaf from iodine solution and rinse it in distilled water.

Answer 2

Answer:-

In the presence of starch iodine solution will turn into blue-black color and in the absence of starch iodine added to leaf will turn into brown color. ... So iodine added in this region will change into brown color. Thus this experiment proves chlorophyll is necessary for leaves to prepare starch through photosynthesis.
