Xanthophyll is blue color in chromatogram 4. There is not a clear division of labour within the chloroplast. 5. Chlorophyll b is the chief pigment associated with photosynthesis.
Options
- AOnly 1 is correct
- BBoth 1 and 2 is correct

Correct answer
A. Only 1 is correct
Step-by-step solution
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 (bright or blue green in the chromatogram), chlorophyll b (yellow green), xanthophylls (yellow) and carotenoids (yellow to yellow-orange).
