Which of the following is incorrect about human eye?
Rod cells sense colour
The iris is the coloured muscular ring that adjusts the size of the pupil to control how much light enters the eye — this statement is correct.
Cone cells are the photoreceptors that work in bright light and are responsible for colour vision — this statement is correct.
Rod cells, not cone cells, are the photoreceptors active in dim light, and they detect only shades of black and white rather than colour, so the claim that rod cells sense colour is incorrect.
The blind spot is the point where the optic nerve leaves the retina; since no photoreceptors are present there, no image can be formed at that spot — this statement is correct.
Hence, the incorrect statement is that rod cells sense colour.
