I gave my students this multiple choice question: Sam was listing the differences between a euglena and a paramecium. Which characteristic should not be on Sam's list?

Only one answer is correct among these 4 choices:
- only the euglena can respond to light
- only the euglena have a definite shape
- only the euglena use a flagellum to move
- only the euglena can make their own food

Could you tell me which one is correct?

only the euglena have a definite shape
