Question

select the correct answer.
seth is chatting with his friends in a café. suddenly, the power goes off, and it’s completely dark. after a few moments, he’s able to see the outlines of the objects and people nearby. which cells are responsible for his ability to see the objects and people?
a. cone
b. glial
c. olfactory
d. rod

Explanation:

In low - light conditions (like when the power goes off and it's dark), rod cells in the retina are responsible for vision. Cone cells are for color vision and work better in bright light. Glial cells support neurons and aren't for vision. Olfactory cells are for smell. So rod cells enable Seth to see outlines in the dark.

Answer:

D. rod
