Assertion : Insects develop a complex system of air tubes called trachea for respiratory purpose.
Reason : Exchange through body surface is not possible in insects.

A

If both the assertion and the reason are true and the reason is a correct explanation of the assertion

B

If both the assertion and the reason are true but the reason is not a correct explanation of the assertion

C

Verified by Experts

The correct Answer is:
A
Air enters the insect body through a row of small breathing pores or spiracles on each side of the abdomen. Each spiracle has a valve which regulates its opening and closing. Air that enters is drawn into the trachea and carried directly to and from cells of the body.

Choose the correct statements regarding Taenia solium I. Scolex is present at the posteriormost end of the body. II. Alimentary canal is absent in all stages of its life cycle. III. Aerobic respiration is found and gaseous exchange takes place through general body surface. IV. The excretory system consists of long canals, capillaris and the protonephridia or flame cells.

Assertion :- In plants there is no need of respiratory and Circulatory system. Reason:- In plants most of the cells have at least a part of their surface in contact with air and an interconnected network of air spaces.

When a person breathers in air, the air enters into his body through an organ A having two holes B in it. The air then passes through pharynx and larynx and enters into a tube C. The tube C divides into two smaller tubes D at its lower end. The two smaller tubes are attached to two respiratory organs E. Each smaller tube divides inside the organs E to form a large number of still smaller tubes called F. The smallest tubes F have air-sacs G at their ends in which gaseous exchange takes place in the body of the person. What are A, B, C, D, E, F and G?
