Question
Which of these are responsible for identification of colors?
- Rod cells
- Nerve cells
- Iris
- Cone cells
Hint:
It is a type of photoreceptor present in the retina.
The correct answer is: Cone cells
- Light reaches the retina at the back of the eye. The retina is covered with millions of light-sensitive cells called rods and cones. When these cells sense light, they send a signal to the brain. Cone cells help distinguish colors.
- Cones are a type of photoreceptor cell in the retina. They help us identify the color. Cones are concentrated in the macula which is the center of the retina and help us see fine details. There are about 120 million rods and 6 million cones in the retina.
