Explanation of Solution

The body plans of most multicellular organisms exhibit some form of symmetry. It includes whether bilateral or spherical and radial. The radial symmetry is suitable for slow-moving organisms such as starfish and free-floating animals such as jellyfish. Especially, the radial symmetry is suitable for sessile animals.

The presence of radial symmetry allows an organism to interact with environments in all directions from one point. The radial symmetry is useful because the animals can just sit down and grab food from all the directions.

The radial symmetry also helps the animals to receive stimuli from all the directions. Thus, it builds up an efficient and strong defense mechanism. Therefore, the presence of radial symmetry is useful for both free-floating and sessile animals.
