Colour vision in bright light is provided by the retinal receptors called
Correct answer: C. cones
- A. rods
- B. bipolar cells
- C. cones
- D. ganglion cells
Explanation
Cones, concentrated in the fovea, work in bright light and distinguish colours in three types. Rods are far more light sensitive and serve dim vision but give no colour, which is why colours fade at dusk.

About Receptors
Receptors are specialized cells or proteins that detect stimuli such as light, sound, pressure, temperature and chemicals, then initiate responses through sensory or hormonal pathways. Questions distinguish sensory receptors from effectors, compare receptor types, and examine stimulus conversion into nerve impulses, including the roles of rods, cones, chemoreceptors and mechanoreceptors.
