(c) How does the eye regulate the amount of light that falls on the retina?
(a) The cones are responsible for colour vision. There are three types of cones cells that respond to green light, blue light and red light according to their characteristics. These cells are stimulated by different sources. The combinations of the signals generated help us see the different colours.
(b) The Inner ear has three semi-circular canals forming a cochlea. The cochlea is responsible for maintaining the balance of the body.
(c) Pupil is the small aperture surrounded by the iris that regulates the amount of light entering the eye. This expands in case of low light and contract in case of intense light thereby regulating the amount of light falling on the retina.
