Cnidarian bodies are either in the polyp or medusa form with tentacles surrounding the mouth. What type of symmetry do they have

kap26 [50]

Answer:- Option a radial symmetry

Explanation:-

Most of the organisms have can either of the two types of symmetry:-

1. Bilateral symmetry- A body is said to have a bilateral symmetry when it can be divided into 2 equal halves on either side of a single plane.

For e.g if you cut the letter M from middle vertically then you have two equal halves.

2. Radial symmetry - A body is said to be radially symmetrical if it can be divided into similar halves in any plane. This means that the organism has its body parts arranged around a central main axis.

The cnidarians whether in polyp or medusa from exhibit radial symmetry because if you cut them in any plane you will get equal halves.
