Question

the cells of the retina in which action potentials are generated are the ______.
rods and cones
bipolar cells
amacrine cells
ganglion cells

Explanation:

To solve this, we recall the function of retinal cells: Rods and cones respond to light (graded potentials, not action potentials). Bipolar cells process signals (graded potentials). Amacrine cells also process (graded potentials). Ganglion cells are the only retinal cells that generate action potentials, as their axons form the optic nerve to transmit signals to the brain.

Answer:

D. ganglion cells
