Solution
The correct sequence of signal transfer in vision is c) photoreceptors --> bipolar cells --> ganglion cells.
Here's the step-by-step process:
-
Light first hits the photoreceptors, which are located in the retina at the back of the eye. There are two types of photoreceptors: rods, which are responsible for vision in low light, and cones, which are responsible for color vision and detail.
-
The photoreceptors then convert the light into electrical signals.
-
These electrical signals are then passed on to the bipolar cells. The bipolar cells are a type of neuron which connect the photoreceptors to the ganglion cells.
-
Finally, the bipolar cells transmit the signals to the ganglion cells. The axons of the ganglion cells come together to form the optic nerve, which carries the visual information to the brain to be processed.
