Directions : In the following questions a statement of Assertion (A) ...
Assertion (A): Cnidarians, Ctenophorans, and Echinoderms show radial symmetry.
Reason (R): Their body can be divided into two equal halves by cutting it in any plane passing through the central axis.
The correct answer is option A: Both Assertion (A) and reason (R) are true, and reason (R) is the correct explanation of Assertion (A).
Explanation:
Radial symmetry is a type of symmetry in which body parts are arranged around a central axis, like the spokes of a wheel. This symmetry allows organisms to interact with their environment equally from all sides. Cnidarians (such as jellyfish and sea anemones), Ctenophorans (comb jellies), and Echinoderms (such as starfish and sea urchins) exhibit radial symmetry.
Reasoning:
The reason provided states that the body of these organisms can be divided into two equal halves by cutting it in any plane passing through the central axis. This is indeed true for organisms with radial symmetry. Unlike organisms with bilateral symmetry, where the body can be divided into two equal halves only by cutting it along a specific plane, organisms with radial symmetry can be divided into equal halves along any plane passing through the central axis. This is because their body parts are arranged symmetrically around the central axis.
Conclusion:
Therefore, the reason provided correctly explains why Cnidarians, Ctenophorans, and Echinoderms show radial symmetry. Their body organization allows for equal division in any plane passing through the central axis. Hence, option A is the correct answer.
Reason (R): Their body can be divided into two equal halves by cutting it in any plane passing through the central axis.
The correct answer is option A: Both Assertion (A) and reason (R) are true, and reason (R) is the correct explanation of Assertion (A).
