Three drops of unboiled chloroplasts were placed in cuvette 2 and 3, and three drops of boiled chloroplasts were placed in cuvette 4. Using the formula Rf one can determine the relationship between the distance the solvent traveled to the distance the pigment traveled. This process of producing their own food is called photosynthesis. In this test it was solubility. Put your strip in it.
