2025 Structural Organisation in AnimalsFrog Respiratory System Medium Question 7 of 92 in Structural Organisation in Animals

Frogs respire in water by skin and buccal cavity and on land by skin, buccal cavity and lungs.
Choose the correct answer from the following:

A The statement is true for water but false for land
B The statement is true for both the environment
C The statement is false for water but true for land
D The statement is false for both the environment

The answer is C.

Solution

In water, frogs respire solely by skin (cutaneous); on land, they respire via skin, buccal cavity, and lungs.

In aquatic conditions, skin serves as the aquatic respiratory organ (cutaneous respiration only). On land, respiration is carried out by skin, buccopharyngeal cavity, and lungs (pulmonary respiration). Hence the statement is false for water but true for land.
