Take a leaf and boil it this is done to kill cells then put it into a test tube filled with alcohol. Now boil it slowly when the alcohol turns green then it means that the chlorophyll has come out. The leaf will turn white. Take the leaf and rinse it . Now put some iodine solution on the leaf the leaf will turn blue_ black which means starch is present in leaf.
