Question

What is monaxial heteropolar symmetry? Name the group of animals in which it is the principle symmetry.

Answer 1

When any plane passing through the central axis of the body divides an organism into two identical parts is called Monaxial heteropolar symmetry. It is the principal symmetry of the diploblastic animals like Cnidarians and ctenophores. 4. Radial symmetry is an advantage to the sessile or slow moving organisms.

Answer 2

Answer:

Monaxial heteropolar symmetry, also known as radial symmetry, is the primary symmetry of diploblastic creatures like cnidarians and ctenophores. It occurs when a plane cuts through the body's central axis and separates an organism into two identical sections.

Explanation:

Monaxial Heteropolar symmetry

• When any plane going through the body's central axis isolates a life form into two identical parts is called Monaxial heteropolar symmetry.
• It is the primary evenness of diploblastic animals like Cnidarians and ctenophores.  
• Radial symmetry: The life form resembles a pie. It can be cut up into roughly identical pieces.
• Bilateral symmetry: There is a pivot on the two sides of the hub. The living being appears to be identical.
• Spherical symmetry: If the living being is sliced through its middle, the subsequent parts appear to be identical
