What type of receptor is responsible for vision?
A
Photoreceptor
B
Chemoreceptor
C
Mechanoreceptor
D
None of the above
Explanation: 

Detailed explanation-1: -Cone cells function under ambient and bright lighting conditions, exhibit rapid responses to variations in light intensity, and are responsible for color vision and high visual acuity.

Detailed explanation-2: -Special cells in the eye’s retina that are responsible for converting light into signals that are sent to the brain. Photoreceptors give us our color vision and night vision. There are two types of photoreceptor cells: rods and cones.

Detailed explanation-3: -The human eye has three different types of light-sensitive receptors: rods, cones and photosensitive ganglion cells.

Detailed explanation-4: -The retina is made up of ten different layers. One of these layers contains special retinal receptors that are light-sensitive cells called photoreceptors. These photoreceptors detect and transform the light coming into the eye into electrical impulses. There are two types of photoreceptors: retinal rods and cones.
