Question

what are photoreceptors how they sense light​

Answer 1

Section 32.3Photoreceptor Molecules in the Eye Detect Visible Light. Vision is based on the absorption of light by photoreceptor cells in the eye. ... Cones function in bright light and are responsible for color vision, whereas rods function in dim light but do not perceive color.

Answer 2

Explanation:

Photoreceptors are the cells in the retina that respond to light. Their distinguishing feature is the presence of large amounts of tightly packed membrane that contains the photopigment rhodopsin or a related molecule. The tight packing is needed to achieve a high photopigment density, which allows a large proportion of the light photons that reach the photoreceptor to be absorbed. Photon absorption contributes to the photoreceptor’s output signal.
