Question

role of the xanthophy ll in photosynthesis​

Answer 1

Explanation:

Xanthophylls (originally phylloxanthins) are yellow pigments that occur widely in nature and form one of two major divisions of the carotenoid group; the other division is formed by the carotenes. The name is from Greek xanthos (ξανθός, "yellow")[1] and phyllon (φύλλον, "leaf"),[2] due to their formation of the yellow band seen in early chromatography of leaf pigments

Answer 2

• Photosynthesis is the conversion of light energy into chemical energy utilized by plants.

• However, each photosynthetic organism must be able to dissipate the light radiation that exceeds its capacity for carbon dioxide fixation before it can damage the chloroplast.

• This photoprotection is mediated by xanthophylls (a group of yellow pigments),which dissipate the thermal radiation from the sunlight through the xanthophyll cycle.
