EVERYDAY SCIENCE

Detailed explanation-1: -Only sponges (phylum Porifera) have asymmetrical body plans. Some animals start life with one type of body symmetry, but develop a different type as adults; for example, sea stars are classified as bilaterally symmetrical even though their adult forms are radially symmetrical.

Detailed explanation-2: -Organisms in phylum Porifera are asymmetrical. Organisms in phylum Cnidaria and Ctenophora are radially symmetrical. Bilateral symmetry is seen in phylum Platyhelminthes and all the following phyla.

Detailed explanation-3: -Sponges are an example of an animal with an asymmetric body.

Detailed explanation-4: -These organisms are radially symmetrical or asymmetrical. The arrangement of body parts in radial symmetry is around a central axis in a way that if they are cut through the center, we will get identical parts. Scypha exhibits a radial symmetry.

Detailed explanation-5: -Honey badgers of the subspecies signata have a second lower molar on the left side of their jaws, but not the right. Humans show a systematic aurofacial asymmetry, meaning that the face (eyes, nose and mouth) are displaced to the left with respect to the midplane between the ears.
