Question

1. Differentiate between rod cells and cone cells.​

Answer 1

Rods Cell

1. Capable of scotopic vision (low light levels), they have a low spatial acuity and do not mediate color
2. Populated at the periphery of the retina.
3. They are rod-shaped, facilitating vision during dim light/night
4. Contain rhodopsin pigment rich in vitamin A responsible for the night vision hence making rods sensitive to light.

Cones Cell

1. Capable of photopic vision(higher light levels), they are responsible for high spatial acuity and responsible for color vision
2. They are populated in the central fovea region and mostly found in retina
3. Help distinguish color and other fine details and are cone-shaped
4. They are of three types – long-wavelength sensitive cones(L-cones), middle-wavelength sensitive cones (M-cones) and short-wavelength sensitive cones (S-cones)
5. These contain iodopsin pigment known as violet pigment

Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity. Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity.
