If the body of an animal can be divided into two indistinguishable left and right halves through only one plane, then it possesses:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 2 i.e. bilateral symmetry.
Animals that can be divided into two identical halves — left and right — through only one plane (the sagittal plane) are said to have bilateral symmetry. This type of symmetry allows for streamlined movement and is seen in most higher animals, including humans, insects, and vertebrates.
Other Options :
-
Asymmetricity: No plane can divide the body into equal halves (e.g., sponges).
-
Centre of symmetry: A geometric term, not used for animal body plans.
-
Radial symmetry: Body parts arranged around a central axis (e.g., jellyfish, starfish).
