Answer:
what cell what what idodod nt understand
Answer:
The human retina has two types of photoreceptors to gather light namely rods and cones. While rods are responsible for vision at low light levels, cones are responsible for vision at higher light levels. The light levels where both are functional are known as mesopic.
Explanation:
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
