Question

Which of these is a type of phycobilin pigments?

• A. Phycocyanin
• B. Allophycocyanin
• C. Phycoerythrin
• D. All of the above

Answer 1

The correct option is D All of the above

Phycobilins are open tetrapyrroles which neither contain magnesium nor phytol. Phycobilins are water soluble. The pigments are of two types-blue (phycocyanin, allophycocyanin) and red (phycoerythrin). The pigments are useful in chromatic adaptations. They are important accessory pigments of blue-green algae, cryptomonas and red algae.

so the correct answer is 'All of the above'.
