My science project is to put a plant in the dark and then in fluorescent light with a black and white photo negative attached. After this, I am supposed to treat the leaf with alcohol and then tincture of iodine over heat to cause the photo image to appear on the leaf. It is a really cool project, but I don't understand how photosynthesis is affecting this. Is it the starch, or is the leaf just acting as a piece of photo paper?
