Solution:
Paper chromatography is a technique used to separate pigments according to their relative solubility and molecular weight. A chromatographic separation of the leaf pigments shows that the colour that we see in leaves is not due to a single pigment but due to four pigments— Chlorophyll a (appears bright or blue green in the chromatogram), chlorophyll b (yellow green), xanthophylls (yellow) and carotenoids (yellow to yellow-orange).
