Which of the following organisms possesses characteristics of both plants and animals?
Correct answer: A. Euglena
- A. Euglena
- B. Paramecium
- C. Bacteria
- D. Mycoplasma
Explanation
Euglenoids have at various times been classiied in the plant kingdom (with algae) and in animal kingdom (in protozoans). Based on molecular data, euglenoids are thought to be closely related to zoolagellates. They are plant like in their pigments. However, some photosynthetic euglenoids lose their chlorophyll when grown in dark and obtain their nutrients heterotrophically by ingesting organic matter. Other species of euglenoids are always colourless and heterotrophic.
