Carotenoid contains:
Correct answer: D. Both (A) and (B)
- A. Carotenes
- B. Xanthophylls
- C. Chlorophyll - C
- D. Both (A) and (B)
Explanation
The carotenoids are divided into two main classes: carotenes and xanthophylls. Carotenes are pure hydrocarbons, meaning they consist only of carbon and hydrogen. Xanthophylls are similar to carotenes but have one or more oxygen atoms in their structure. Although both are types of carotenoids, chlorophylls, such as chlorophyll - C, are not related to carotenoids but are rather a different group of pigments involved in photosynthesis. Therefore, the correct answer is that carotenoids contain both carotenes and xanthophylls.
