Question

Accessory pigments:

• A. play no role in photosynthesis.
• B. release $e^{-}$ and get oxidized.
• C. transfer of $e^{-}$ to NADP.
• D. allow plants to harvest visible light of wider range wavelengths.

Answer 1

Answer: (D)

Accessory pigments are light-absorbing compounds that traps light energy and channels it to chlorophyll a which initiates the reactions of photosynthesis. Accessory pigment includes the carotenoids, phycobiliproteins, and chlorophylls $b,c,$ and $d$. Indeed, they not on enable a wider range of wavelength of incoming light to be utilized for photosynthesis but also protect chlorophyll a from the photo-oxidation.
