What is the main function of photoreceptor cells in the retina?
Answer and explanation
Correct answer: To convert light into nerve signals
The governing concept is sensory transduction in vision. Retinal photoreceptors, mainly rods and cones, absorb light and convert its energy into electrical changes that begin nerve signals. These signals are processed in the retina and carried toward the brain through the optic nerve. Therefore option A is correct; filtering blood, joining bones, and producing taste are functions of other body structures.
