Biologists divide photosynthetic protists based on various aspects. Which one of these pairs, when classified based on pigments, is mismatched?
Correct answer: C. Euglenophyta
- A. Pheophyta
- B. Rhodophyta
- C. Euglenophyta
- D. Chlorophyta
Explanation
The mismatched pair is Euglenophyta, because euglenoids are mainly classified based on storage products and body form, not pigments. Pheophyta (brown algae), Rhodophyta (red algae), and Chlorophyta (green algae) are correctly classified by their pigments. Thus, Euglenophyta does not fit when grouping photosynthetic protists by pigments.
