Based on molecular data euglenoids are thought to be closely related to___________?
Correct answer: B. Zooflagellates
- A. Dinoflagellates
- B. Zooflagellates
- C. Protozoans
- D. Algae
Explanation
Molecular evidence has traditionally placed euglenoids close to zooflagellates, particularly because of shared flagellated and cellular features in older classification systems. Students may choose algae because many euglenoids photosynthesize, but photosynthesis alone does not establish their closest evolutionary relationship. The submitted key matches.
