Chlorophyll can be shown to be vital for photosynthesis by destarching a leaf from a [[variegated plant]] and exposing it to light for several hours. (Variegated leaves have green areas that contain chlorophyll and white areas that have none.) When tested with [[iodine solution]], a color change revealing the presence of starch occurs only in regions of the leaf that were green and therefore contained chlorophyll. This shows that photosynthesis does not occur in areas where chlorophyll is absent and constitutes evidence that the presence of chlorophyll is a requirement for photosynthesis.
