Any two function of photoreceptor cell

The function of the photoreceptor cell is to convert the light energy of the photon into a form of energy communicable to the nervous system and readily usable to the organism: This conversion is called signal transduction.

There are two types of photoreceptors in the human retina, rods and cones. Rods are responsible for vision at low light levels (scotopic vision). ... Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity.

I hope this helps in some way :)
