Which statement describes Cones?

• A. They are responsible for night vision
• B. They detect light intensity
• C. They are located in the cornea
• D. They are light sensitive cells that respond to color

Answer: (D)

Cones are photoreceptor cells in the retina that respond to color. They are light sensitive and come in three types, each tuned to red, green, or blue light, which lets us see a wide range of colors and discern fine detail in bright light. They’re concentrated in the fovea centralis, giving sharp, color-rich vision. They are not located in the cornea—the cornea is the front surface of the eye that helps focus light but has no photoreceptors. Night vision is provided mainly by rods, which detect light intensity in low light but don’t detect color. That’s why the statement that cones are light sensitive cells that respond to color is the best description.
