Question

Which is radially symmetrical and diploblastic?

Answer 1

Radially symmetrical:

When any plane traveling through the central axis of the body can divide the organisms into two equal half, it is said to be radially symmetrical.

Explanation:

1. Ctenophores, echinoderms, and other organisms have radial symmetry.
2. When an animal's embryonic germ layers are separated into two layers, external ectoderm and internal endoderm, it is said to be diploblastic.
3. Mesoglea is an undifferentiated layer that exists between the two layers in such animals.
4. Coelenterata creatures have both radial symmetry and diploblastic characteristics.
5. Hydra, jellyfish, Aurelia, Physalia, and Adamsia are examples of coelenterates.
6. Bilaterally symmetrical animals have bodies that may be divided into two identical left and right halves by only one plane.
7. Annelids, arthropods, and other organisms are examples.
