Classification of algae is largely based on
Correct answer: A. Their pigment composition
- A. Their pigment composition
- B. Thallus
- C. Mode of reproduction
- D. All of these
Explanation
Algae are classified mainly based on their pigment composition because the pigments determine the absorption of light and thus the ecological niche and evolutionary adaptations of the algae. Pigments like chlorophylls, carotenoids, and phycobilins are key identifiers. The thallus structure and reproduction modes are secondary characteristics and do not primarily dictate classification. Therefore, the correct answer is Option A: Their pigment composition.
