Correct Answer
(1) carotenoids
Explanation
Carotenoids are the yellow and orange accessory pigments found in chloroplasts alongside chlorophyll. They include:
- Carotenes — orange pigments (e.g., beta-carotene)
- Xanthophylls — yellow pigments
Carotenoids assist in capturing light energy and protecting chlorophyll from light-induced damage. They become visible in autumn leaves as chlorophyll breaks down.
