Question

Match the senses with their respective sensory organs present in frog:

1. Touch	i. Tympanum
2. Taste	ii. Nasal epithelium
3. Smell	iii. Taste buds
4. Vision	iv. Simple eyes
5. Hearing	v. Sensory papillae

• A. i-1, ii-2, iii-5, iv-3, v-4
• B. i-2, ii-3, iii-5, iv-1, v-4
• C. i-5, ii-3, iii-2, iv-4, v-1
• D. i-1, ii-5, iii-4, iv-2, v-3

Answer 1

The correct option is C i-5, ii-3, iii-2, iv-4, v-1

Frog has different types of sense organs,
i. Touch - Sensory papillae
ii. Taste - Taste buds
iii. Smell - Nasal epithelium
iv. Vision- Simple eyes
v. Hearing- Tympanum
Eyes (simple eyes) and internal ears are well-organised structures whereas the rest of them are just cellular aggregates around nerve endings. There is no external ear in frogs and only the tympanum can be seen externally which is responsible for hearing and equilibrium.
