Question

Is Xanthophyll an accessory pigment?

Answer 1

Hint: Plant pigments are chromogenic or colored substances synthesised by plants that have a role in photosynthesis, growth, and development. Plant pigments are divided into two categories: tetrapyrroles (such as chlorophyll) and carotenoids (such as -carotene and xanthophyll). Green plant pigments absorb light and convert it to adenosine triphosphate (ATP) chemical energy via the linked systems of chloroplasts.

Complete answer:
Yes, Plants produce xanthophylls, which are secondary pigments.
Many yellow, orange, and red-colored fruits, flowers, and vegetables contain xanthophylls, which are yellow-colored pigments.
Many of the yellow, orange, and red colours of flowers, fruits, and vegetables are due to xanthophylls, a family of oxygen-containing carotenoid pigments (corn, pepper, etc.). They participate in photosynthesis with chlorophyll in plants and are responsible for the red, yellow, and/or brown hues of autumn foliage when chlorophyll levels fall.
Xanthophyll pigments play structural and functional roles in algae and vascular plants' photosynthetic light-harvesting complexes.
The bulk of xanthophylls are coupled with chlorophyll (Chl) molecules to proteins of integral membrane, light-harvesting complexes (LHCs) where they serve as accessory pigments in virtually all photosynthetic eukaryotes.

Note:
Accessory pigments are light-absorbing molecules that operate in tandem with chlorophyll in photosynthetic organisms. Plant pigments, such as chlorophyll b in green algal and higher plant antennae, as well as chlorophyll c and d in other algae, are also accessory pigments. Furthermore, there are a large number of non-chlorophyll accessory pigments, such as carotenoids and phycobiliproteins that absorb light and transport it to the photosystem chlorophyll.
