Question

Some sponges are radially symmetrical

(a) True

(b) False

The question was posed to me during an interview.

Origin of the question is Classification of Animal Kingdom into Different Phylum-1 topic in section Animal Kingdom of Biology – Class 11

Answer 1

Right answer is (a) True

For explanation I would say: Most of the sponges are asymmetric whereas few sponges are radially symmetrical.  For example, in case of sea stars bilateral symmetry is seen in the initial stage and radial symmetry in adult forms.
