Q. No.Accessory pigments are essential in photosynthesis primarily because they:
1. Replace chlorophyll a at the reaction centre
2. Enable absorption of a wider range of wavelengths and prevent photo-oxidation
3. Participate directly in CO2 fixation reactions
4. Convert light energy into ATP independently
