Question

Identify type of symmetry in the given animals A and B.

• A. A - Bilateral, B - Asymmetrical
• B. A - Bilateral, B - Bilateral
• C. A - Radial, B - Bilateral
• D. A - Radial, B - Radial

Answer 1

Answer: (C)

A - Radial, B - Bilateral

• Radial Symmetry: The organism's body generates identical sides in any plane in which it is divided along the central axis.
• Bilateral Symmetry: The body of the organism generates two sides as left and right along the sagittal plane. Both sides are mirror images of each other.

Figure 'A' is of Hydra which exhibits radial symmetry and figure 'B' is of crab which exhibits bilateral symmetry.

Hence, the correct answer is option 'C'.
