A paramecium does not live where there is light. A paramecium does not photosynthesize its own food. A paramecium lives in shallower water than a euglena. A paramecium uses cilia instead of a flagellum to move.
I gave my students this multiple choice question: A euglena cell has a structure called an eyespot that detects light. A paramecium does not have an eyespot, and so it cannot detect light. Why doesn't a paramecium need an eyespot?

Only one answer is correct among these 4 choices:
- A paramecium does not live where there is light.
- A paramecium does not photosynthesize its own food.
- A paramecium lives in shallower water than a euglena.
- A paramecium uses cilia instead of a flagellum to move.

Could you tell me which one is correct?

A paramecium does not photosynthesize its own food.
