eyespot cell wall chloroplast central vacuole
I gave my students this multiple choice question: Both euglenas and volvox are classified as plant-like protists. But volvox has more structures in common with plants than euglenas do. Which structure found in plant cells is also found in volvox but not in euglenas?

Only one answer is correct among these 4 choices:
- eyespot
- cell wall
- chloroplast
- central vacuole

Could you tell me which one is correct?

cell wall
