Question types: The eye and the ear
Rule: Sense organs
Eye: the cornea and lens bend light, the iris changes the size of the pupil, the image forms on the retina.
Ear: the eardrum vibrates, three tiny bones pass the vibrations on, the cochlea turns them into nerve signals.
Example: The semicircular canals in the inner ear help you keep your balance.
Watch out: The pupil is not the coloured part of the eye: that is the iris; the pupil is the black hole in the middle.
Sample questions
-
Question 1 Easy
What does this part of the eye or ear do? Match each item (1–3) with the right option (A–D).
- ear bones (hammer, anvil, stirrup)
- eardrum
- cochlea
Show the solution
Answer:- ear bones (hammer, anvil, stirrup) → A) pass the vibrations on to the inner ear
- eardrum → C) vibrates when sound reaches it
- cochlea → B) contains the hearing cells
How it works: ear bones (hammer, anvil, stirrup) – pass the vibrations on to the inner ear; eardrum – vibrates when sound reaches it; cochlea – contains the hearing cells

Question 2 Normal
What does this part of the eye or ear do? Match each item (1–4) with the right option (A–E).
- semicircular canals
- cochlea
- iris
- optic nerve
Show the solution
Answer:- semicircular canals → E) sense balance
- cochlea → A) contains the hearing cells
- iris → C) gives the eye its colour and changes the size of the pupil
- optic nerve → D) carries signals from the eye to the brain
How it works: semicircular canals – sense balance; cochlea – contains the hearing cells; iris – gives the eye its colour and changes the size of the pupil; optic nerve – carries signals from the eye to the brain

Question 3 Hard
What does this part of the eye or ear do? Match each item (1–5) with the right option (A–F).
- lens
- cochlea
- optic nerve
- eardrum
- retina
Show the solution
Answer:- lens → D) bends light and focuses the image
- cochlea → C) contains the hearing cells
- optic nerve → A) carries signals from the eye to the brain
- eardrum → F) vibrates when sound reaches it
- retina → E) contains light-sensitive cells (rods and cones)
How it works: lens – bends light and focuses the image; cochlea – contains the hearing cells; optic nerve – carries signals from the eye to the brain; eardrum – vibrates when sound reaches it; retina – contains light-sensitive cells (rods and cones)
