D.
Chlorophyll a-700, chI. a-880, chI. b, chI. a-685 and phycobilins
Answer: Option A
Solution
Answer: Option A
Solution:
Photosystem has main light harvesting pigments, Chlorophyll a-660, chI. a-670, chI. a-680, chI. a-690, chI. a-700.Chlorophyll a is a specific form of chlorophyll used in oxygenic photosynthesis. It absorbs most energy from wavelengths of violet-blue and orange-red light, and it is a poor absorber of green and near-green portions of the spectrum.
Chlorophyll a also transfers resonance energy in the antenna complex, ending in the reaction center where specific chlorophylls P680 and P700 are located.
