In the retina of the human eye, the COLOUR + sharp daylight vision is mediated by:
ARods (for low-light black-and-white vision)
BCornea (the outer transparent layer)
CCones (for daylight + colour vision)
DIris (controls pupil aperture only)
Answer & Solution
Correct answer: C. Cones (for daylight + colour vision)
CONES: photoreceptors for colour + sharp vision; concentrated in the fovea. RODS: more sensitive, low-light + black-white. Humans have 3 cone types: red, green, blue sensitive. Colour blindness = defective cone.
