Detailed explanation-1: -The cone cells are of three types: Red (R), Green (G) and Blue (B) cells. Each type of cone cell responds to a range of wavelengths, with a particular wavelength showing the maximum response.

Detailed explanation-2: -A special property of the cone system is color vision. Perceiving color allows humans (and many other animals) to discriminate objects on the basis of the distribution of the wavelengths of light that they reflect to the eye.

Detailed explanation-3: -Rods don’t help with color vision, which is why at night, we see everything in a gray scale. The human eye has over 100 million rod cells. Cones require a lot more light and they are used to see color.

Detailed explanation-4: -Cone cells are responsible for our central vision, along with helping us to see colour and objects in detail under bright light. The number of cone cells in human is less compared to rods and they are mainly situated in the fovea.

Detailed explanation-5: -Cones are a type of photoreceptor cell in the retina. They give us our color vision. Cones are concentrated in the center of our retina in an area called the macula and help us see fine details. The retina has approximately 120 million rods and 6 million cones.
