What is a sponge's symmetry like?

Answer 1

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).

Answer 2

Sponges are asymmetrical.

There is no symmetry of a sponge body because the sponge grows to fit the space where they live

Answer 3

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

Answer 4

Sponges show no symmetry: they are asymmetrical.

Answer 5

Sponges are considered to be asymmetrical. Their body is not organised in any particular pattern.

Answer 6

None. It is said to be asymmetrical.

Answer 7

Radial

Answer 8

asymmetrical
