Yellow Encrusting Sponge Myxilla lacusnosa Sponges are the simplest of the multicellular animals. They have no organ systems and are characterized by numerous canals and chambers that open to the outside by way of pores which giving this phylum its name. Many sponges are asymmetrical, but some exhibit radial symmetry. They are almost plant-like in their simplicity and are often confused as being plants. The body plan of a typical sponge is shown in figure1. Water (carrying suspended plankton and other potential food) enters numerous small pores called ostia (singular, ostium). The ostia are surrounded by donut-shaped cells called porocytes that open and close to control water flow. For the sponge depicted in figure 1, water flows directly into an open chamber called the spongocoel (the term "coel" refers to an open space or body cavity in an animal). Water leaves the spongocoel by a larger opening (the osculum).

What kind of symmetry do sponges exhibit?

Sponges are asymmetrical, although a few species have nearly radial symmetry.


What is a sponge like?

Sponges mostly have no symmetry, but it is possible to have a sponge that exhibits radial symmetry. They never have bilateral symmetry.


Almost all animals except what have either radial or bilateral symmetry?

Almost all animals except sponges have either radial or bilateral symmetry. Sponges belong to the phylum Porifera, characterized by their lack of symmetry.


Is a sponge bilateral symmetry or radial symmetry?

Sponges really don't have any kind of symmetry.


Is a sponge a bilateral symmetry or a radial symmetry?

Sponges really don't have any kind of symmetry.


What is the type of symmetry of a sponge?

Sponges exhibit a type of symmetry known as asymmetry. Unlike many other animals, sponges do not have a defined shape or symmetry, as they can vary greatly in form and structure. Some sponges may exhibit a degree of radial symmetry, but overall, they lack the organized symmetry seen in more complex organisms.


What kind of organisms are in bilateral symmetry?

Sponges


What type of symmetry do sponges exhibit How does this differ from organisms belonging to phylum Cnidaria Arthropoda?

Sponges exhibit asymmetry, meaning they lack any distinct symmetry. In contrast, organisms from phylum Cnidaria and Arthropoda typically exhibit radial symmetry (such as jellyfish) or bilateral symmetry (like butterflies), respectively, where body parts are arranged around a central axis or mirror images are present on either side of the body.


What type of symmetry are sponges?

an asymmetrical body plan


Is a sponge a bilateral or radial?

Sponges are asymmetrical. They have no symmetry.


What Sponges like the one pictured demonstrate symmetry.?

The sponge in the picture exhibits radial symmetry, which means it can be divided along several planes to create similar halves. Radial symmetry is common in sessile organisms like sponges, where their body parts are arranged around a central axis, allowing them to capture food efficiently from all directions.
