Differentiate between Rods and cones
Rods Capable of scotopic vision (low light levels), they have a low spatial acuity and do not mediate color Populated at the periphery of the retina. They are rod-shaped, facilitating vision during dim light/night Contain rhodopsin pigment rich in vitamin A responsible for the night vision hence making rods sensitive to light Cones Capable of photopic vision(higher light levels), they are responsible for high spatial acuity and responsible for color vision They are populated in the central fovea region and mostly found in retina Help distinguish color and other fine details and are cone-shaped They are of three types – long-wavelength sensitive cones(L-cones), middle-wavelength sensitive cones (M-cones) and short-wavelength sensitive cones (S-cones) These contain iodopsin pigment known as violet pigment
