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 am hesitating between 4 options to answer the following question, which option should I choose?
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?
Possibilities:
- 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.

A paramecium does not photosynthesize its own food.
