Which of the following is the main function of Xanthophylls?
1 Helps the plant from photo-damage
2 Not an accessory pigment
3 Helps in photosynthesis
4 Helps in photo-respiration
Explanation:
Xanthophylls are accessory pigments. They not only enable a wider range of wavelength of incoming light to be utilized for photosynthesis but also protect chlorophyll-a from photooxidation.

Which is false regarding chlorophyll-a and chlorophyll-b?
1 Chlorophyll-a is the main chief pigment in photosynthesis
2 Chlorophyll-b is the accessory pigment
3 Both are present in equal proportion
4 All are correct
Explanation:
Chlorophyll-a is the chief pigment present in all photosynthetic organisms. Chlorophyll-b is an accessory pigment present in lesser amounts compared to chlorophyll-a.

1 A-Q , B-P , C-R , D-S
2 A-P , B-Q , C-R , D-S
3 A-P , B-R , C-S , D-Q
4 A-R , B-S , C-P , D-Q
Explanation:
A. Xanthophylls, Carotenoids - P. Accessory pigments B. Chlorophyll-a,b - Q. Essential pigments C. Emerson effect - R. Photosystems D. Chlorophyll-a - S. Reaction centre Emerson effect is the increase in the rate of photosynthesis after chloroplasts are exposed to the light of wavelength 680nm and more. The effect was an early evidence that two photosystems, processing different wavelengths cooperate in photosynthesis.
