Question

Is Porifera radial symmetry?

Answer 1

Porifera:

1. These are multicellular animals that are organized at the cellular level.
2. Sponges have a canal system for transportation. Water enters the body wall through minute holes (Ostia) and flows into the spongocoel, a central chamber from which it exits through the osculum.
3. Food collecting, respiratory exchange, and waste elimination are all aided by this water transport system.

Symmetry:

1. Porifera is mostly asymmetrical.
2. Asymmetrical means that any plane traveling through the body's central axis does not divide the organism into two equal halves.
