Which of the following pairs of leaf pigments and their corresponding colour observed on a paper chromatogram is incorrectly matched?

Options

  1. AChlorophyll a : Bright or blue green
  2. BXanthophyll : Bright green
  3. CChlorophyll b : Yellow green
  4. DCarotenoids : Yellow to yellow-orange

Correct answer

B. Xanthophyll : Bright green

Step-by-step solution

According to the chromatographic separation of leaf pigments, the correct colours are: Chlorophyll a appears bright or blue green. Chlorophyll b appears yellow green. Xanthophylls appear yellow. Carotenoids appear yellow to yellow-orange. Therefore, the pairing of Xanthophyll with 'Bright green' is incorrect. Answer: Xanthophyll : Bright green
