Hint: The eye is an organ of sight that acts like a camera shutter. It detects the light and converts it into electro-chemical impulses in neurons.

Complete answer:
The eye is a sensory organ that enables us to see the things around us.
The difference between the iris and pupil are as follows:
Iris Pupil
The iris is the ring-shaped membrane inside the eye.The pupil is the black hole or opening present in the center of the iris.
It surrounds an opening in the center called the pupil.It is surrounded by the tissues of iris.
It regulates the amount of light to enter the eye.It is the opening through which the light enters our eye.
It contains the muscles that contract when the light is bright and relaxes when the light is low.As it is a hole it does not contain any kind of tissue.
It determines the color of our eye.It is not responsible for determining the color of our eye.
It is a curtain-like patch of tissues in our eye.It is like a gap between the two curtains like a patch of tissues in our eye.
The amount of light reaching the retina of our eye is controlled by the iris.It allows the light to strike the retina.


Note: -Iris focuses the light rays onto the retina so that the image will be formed and we can see things properly.
-The iris muscles allow the pupil to become larger and smaller.
-Depending upon the amount of light fling in our eye, the iris control the widening and tapering of the pupil in our eye.
