Question

what is the difference between biradial and bilateral symmetry??

Answer 1

As-Salamu-Alykum



__________

Bilateral symmetry means symmetry through which a body can be divided into two equal parts .

Radial symmetry means in which body can be divided in different axis .

Biradial symmetry means combination of both of these that is radial and bilateral symmetry

Remember that just Phyllum Celentrated are Radially symmetrical

Answer 2

Biradial symmetry is a combination of radial and bilateral symmetry, as in the ctenophores. Here, the body components are arranged with similar parts on either side of a central axis, and each of the four sides of the body is identical to the opposite side but different from the adjacent side. This may represent a stage in the evolution of bilateral symmetry "from a presumably radially symmetrical ancestor.
In bilateral symmetry (also called plane symmetry), only one plane, called the sagittal plane, divides an organism into roughly mirror image halves. Thus there is approximate reflection symmetry. Internal organs are however not necessarily symmetric.
