Verified step by step guidance

Understand the function of each type of cell in the retina: Cones, Rods, Bipolar cells, and Ganglion cells.

Cones are photoreceptor cells in the retina that are responsible for color vision and function best in bright light. They are sensitive to different wavelengths of light, which allows us to perceive colors.

Rods are another type of photoreceptor cell in the retina, but they are more sensitive to low light levels and do not distinguish colors. They are primarily responsible for night vision.

Bipolar cells are intermediary cells in the retina that transmit signals from the photoreceptors (rods and cones) to the ganglion cells. They do not directly detect light or color.

Ganglion cells receive visual information from the bipolar cells and transmit it to the brain via the optic nerve. They are not directly involved in distinguishing wavelengths of light.
