Question

Pigments present in cones of retina are connected with _______.

• A. Night blindness
• B. Accommodation of eye
• C. Colour discrimination
• D. Image formation

Answer 1

Answer: (C)

Colour discrimination

The retina of eye has two types of photoreceptor cells: rods and cones.

• Rods are the photoreceptor cells that contain rhodopsin pigment and associated with scotopic vision of eye i.e. vision under low light.
• Cones are the photoreceptor cells that contain iodopsin, porpyrosin and cyanopsin pigments. These cells are associated with the daylight vision and colour vision of eyes.

Hence, pigments present in cones of retina are connected with colour discrimination.

So, the correct answer is 'Colour discrimination'.
