Verified step by step guidance

Understand the function of photoreceptor cells in the retina: Photoreceptor cells are specialized neurons found in the retina of the eye that are responsible for converting light into signals that can be interpreted by the brain.

Identify the types of photoreceptor cells: The two main types of photoreceptor cells are rods and cones. Each type has a distinct role in vision.

Explore the role of rods: Rods are highly sensitive to low light levels and are primarily responsible for night vision. They do not detect color but are crucial for seeing in dimly lit environments.

Explore the role of cones: Cones are responsible for color vision and function best in bright light. They are less sensitive to low light levels compared to rods.

Differentiate other retinal cells: Ganglion cells and bipolar cells are not photoreceptors. Ganglion cells transmit visual information from the retina to the brain, while bipolar cells act as intermediaries between photoreceptors and ganglion cells.
