Question

Match the following:
$\begin{array}{cc}\text{Part of eye}& \text{Function}\\ a)\text{Iris}& p)\text{Converts the light into neural signals, and sends}\\ & \text{these signals to the brain for visual recognition}.\\ b)\text{Lens}& q)\text{It bends the light onto the lens.}\\ c)\text{Retina}& r)\text{Controls size of pupil and amount of light reaching}\\ & \text{the retina.}\\ d)\text{Cornea}& s)\text{Focuses light onto the retina and helps the eye to}\\ & \text{focus objects at different distances.}\end{array}$

• A. a-r, b-s, c-p, d-q
• B. a-r, b-q, c-p, d-s
• C. a-p, b-s, c-q, d-r
• D. a-r, b-s, c-q, d-p

Answer 1

The correct option is A a-r, b-s, c-p, d-q

Following are the functions of different parts of the eye:
Iris: It is the coloured portion of the eye. It controls the amount of light reaching the retina by regulating the size of pupil.
Lens: The converging lens can adjusts its shape to focus the light on retina.
Retina: It converts light signals into nerve impulses and sends these signals to brain for visual recognition via optic nerve.
Cornea: It is the outer covering of the eye. It bends the incoming light rays and focusses them on the lens.
