Assertion : Insects develop a complex system of air tubes called trach...
Assertion Explained: Tracheal System in Insects
Insects possess a unique respiratory system that is highly efficient for their small size. They develop a network of air tubes known as tracheae, which facilitate direct gas exchange.
Function of Trachea:
- The trachea allows oxygen to diffuse directly into tissues and carbon dioxide to diffuse out, bypassing the need for a circulatory system for gas transport.
- This system is composed of tiny openings called spiracles located on the insect's body surface, leading into the tracheal tubes.
Reasoning Behind the Assertion:
- The assertion states that insects have evolved this complex system primarily because gas exchange through the body surface is ineffective for them.
- Insects have a tough outer exoskeleton, which limits the ability of gases to diffuse across their body surface. Thus, a specialized system like tracheae is essential.
Conclusion:
- Both the assertion and the reason are true.
- The reason accurately explains why insects developed the tracheal system; the limitations of gas exchange through the body surface necessitated a more sophisticated method.
Final Answer: Option A
- Therefore, the correct option is 'A': both the assertion and the reason are true, and the reason correctly explains the assertion.

Assertion : Insects develop a complex system of air tubes called trach...
As the integument of insect is thick and impermeable to minimise lose of body water, they can not carry out gas exchange through their body surface. To overcome this difficulty they have developed a complex system of air tubes called trachea to reach the air directly near the tissue cells. Each trachea communicates with the exterior through openings in the body wall.
