Assertion : Respiration is most efficient in the insects. Reason : In insects air is carried directly to the cells by tracheoles.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Respiration is more efficient in insects because of following reasons An internal gas exchange system with an impermeable exoskeleton and spiracles that can open and close helps to protect gas exchange system and prevent water loss, allowing insects to live in some of the driest places on earth. • Short diffusion distance for gases to move through tracheoles means that no transport system is required (saves space, weight and energy). Oxygen moves down tracheoles by passive diffusion, dissolves into the fluid at the end of each tube and diffuses directly into each cell. Therefore, oxygen reaches the respiring cells more quickly. • Rhythmic contractions of abdominal muscles compress air sacs increasing ventilation which helps to maintain a concentration gradient during vigorous activity such as flying. This increases the rate of gas exchange when the insect is more active and has an increased metabolic demand (needs more oxygen).
