검증된 단계별 안내1
Understand the function of photoreceptors in the human eye: Photoreceptors are specialized cells in the retina that respond to light. There are two main types: rods and cones.
Identify the role of rods: Rods are responsible for vision in low light conditions and are sensitive to black, white, and shades of gray. They do not detect color.
Identify the role of cones: Cones are responsible for color vision and function best in bright light. They are sensitive to different wavelengths corresponding to colors.
Differentiate between other retinal cells: Bipolar cells and ganglion cells are not photoreceptors. They are involved in the processing and transmission of visual information from photoreceptors to the brain.
Conclude that rods are the photoreceptors responsible for black, white, and gray vision, as they are specifically adapted for low-light and non-color vision.
