Question

Give an account of different types of body planes in animals

Answer 1

Mainly two body planes are considered

1) When any plane passing through central axis of the body divides the organism in to two identical halves it is called radial symmetry examples Coelenterates , ctenophores, echinoderms have this kind of body plan.
2)Animals like annelids, arthropods, etc .,where body can be divided into two identical left and right halves in only one plane is known to be bilateral symmetry.
Sponges are mostly asymmetrical i.e., any plane passing through the centre does not divide them into equal halves.

Answer 2

Answer:

Animal body plans follow set patterns related to symmetry. They can be asymmetrical, radial, or bilateral in form

1. Asymmetrical animals are those with no pattern or symmetry, such as a spong.
2. Radial symmetry describes an animal with an up-and-down orientation.
3. Bilateral symmetry is found in both land-based and aquatic animals; it enables a high level of mobility.

This is the right and proper answer
