Carotenoid pigments are present in:
Correct answer: D. Both A and B
- A. Euglenophyta
- B. Pyrrophyta
- C. Chrysophyta
- D. Both A and B
Explanation
Euglenophyta, commonly known as euglenoids, are a group of unicellular organisms that possess chloroplasts and are capable of photosynthesis. They contain various pigments, including carotenoids, which contribute to the coloration of these organisms. Pyrrophyta, also known as dinoflagellates, are another group of unicellular organisms. Pyrrophyta also contains carotenoid pigments, which give them their characteristic colors. Therefore, carotenoid pigments are found in both Euglenophyta and Pyrrophyta.
