- A Mode of locomotion, pseudopodia versus flagella
- B Cell wall composition, cellulose versus chitin
- C Mode of nutrition, autotrophic versus chemosynthetic
- D Habitat, exclusively marine versus exclusively terrestrial
Correct answer: A. Mode of locomotion, pseudopodia versus flagella
Explanation: Entamoeba is an amoeboid protozoan that moves using pseudopodia, while Trypanosoma is a flagellated protozoan that moves using flagella. Both are heterotrophic, parasitic protists causing disease in humans.
