Which of the following structures is most likely to be found in an autotrophic protist?
a. a gullet
b. a chloroplast
c. a food vacuole
d. a plasmodium

The right answer is the chloroplast.

Autotrophic species must stock up on food in order to have energy at all times.

Plants, for example, through their chloroplasts make sugar with the energy of sunlight and from soil water and carbon dioxide from the air. This sugar synthesis using light is photosynthesis.
