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?
choices.text: 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.
