Question

Which of the following options is/are correct for accessory photosynthetic pigments ?

• A. They include chlorophyll- b, xanthophylls and carotenoids
• B. They absorb light and transfer to chlorophyll- a
• C. They enable absorption of wider range of wavelength of incoming light for photosynthesis
• D. All of the above

Answer 1

Answer: (D)

Chlorophyll- $b$, xanthophylls and carotenoids are called accessory pigments of photosynthesis. These pigments absorb light and transfer the energy to chlorophyll- $a$. They enable a wider range of wavelength of incoming light to be utilised for photosynthesis but also protect chlorophyll- $a$ from photooxidation.
