Question

Chlorophyll a appears ............. in colour and chlorophyll b appears ................ in color in the chromatogram.

• A. Bluish green, yellowish green
• B. Yellowish green, bluish green
• C. Blue, blue
• D. Green, green

Answer 1

The correct option is A Bluish green, yellowish green

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 color 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)

carotenoids (yellow to yellow-orange).

So the correct answer is 'Bluish green, yellowish green'.
