Question

Animals which see well during night have abundant _______.

• A. Rods
• B. Cones
• C. Scotopic cells
• D. Night vision cells

Answer 1

The correct option is A Rods

Vision of eye occurs because of 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, animals which see well during night have rods.

So, the correct answer is 'Rods'.
