No one organism really needs symmetry. When you think of symmetry though, you usually think of bilateral symmetry. This is when two sides of an organism are almost identical. The sponge just grows whichever way it pleases.
A sponge has no symmetry, and is therefore asymmetrical.
Sponges mostly have no symmetry, but it is possible to have a sponge that exhibits radial symmetry. They never have bilateral symmetry.
Radial symmetry or Assymmetry
A sponge has no symmetry, radial or bilateral.
no, it is asymmetrical
yes
Sponges really don't have any kind of symmetry.
Sponges really don't have any kind of symmetry.
One animal that has radial symmetry is a sea sponge.
A sponge has an asymmetrical symmetry. So they don't have a definite shape.
Sponges are asymmetrical. They have no symmetry.
The sponge is considered to be asymmetrical because it is not a perfect shape, and it is generally an off shape.
