Step 1: Defining cones in the eye.
The cones are photoreceptor cells in the retina that are sensitive to light. There are three types of cones, each sensitive to different wavelengths of light, which correspond to the colors red, green, and blue.
Step 2: Function of cones.
Cones are responsible for color vision, allowing humans to perceive a wide spectrum of colors. They also work best in well-lit conditions, unlike rods, which are more sensitive in low-light conditions.
Step 3: Conclusion.
Cones detect specific colors based on the light's wavelength, allowing the brain to process and perceive color. They are essential for the visual identification of colors in bright light.
