How would you describe the symmetry of the sponge body?
How would you describe the symmetry of the sponge body?
Sponges have asymmetrical symmetry. When an animal’s body shape is asymmetrical, there is no axis or line that can be drawn where it is essentially…
Does a sponge lack symmetry?
Sponges lack true tissues, have no body symmetry, and are sessile; types are classified based on presence and composition of spicules.
What type of symmetry do fish have?
Bilateral symmetry
Bilateral symmetry is characteristic of the vast majority of animals, including insects, fishes, amphibians, reptiles, birds, mammals, and most crustaceans.
Do all sponges have radial symmetry?
Most are sponges are asymmetrical, though some of them exhibit radial symmetry (Dawkins 2004). There are so many types of animals that do not have body symmetry.
Why are the sponge is mostly asymmetrical?
They are underwater organisms that lack true tissues and organs. They do not have a digestive or circulatory system and respiration takes place by water diffusion. And their life functions take place through central cavities and pores by diffusion. Hence, their symmetry will be decided by their functions and structure.
How do you create symmetry?
To draw in Symmetry mode
- Click Object > Symmetry > Create New Symmetry. A symmetry line appears in the drawing window.
- Draw a curve or a shape. In the following example, the 3-point curve tool is used to draw a curve.
- You can edit the shape of the curve with the Shape tool .
Are most sponges asymmetrical?
Sponges are similar to other animals in that they are multicellular, heterotrophic, lack cell walls and produce sperm cells. Unlike other animals, they lack true tissues and organs. Some of them are radially symmetrical, but most are asymmetrical.
What kind of symmetry does a sponge have?
Only members of the phylum Porifera (sponges) have no body plan symmetry. There are some fish species, such as flounder, that lack symmetry as adults. However, the larval fish are bilaterally symmetrical. Beside above, do snails have radial symmetry?
Are there any fish that lack symmetry as an adult?
There are some fish species, such as flounder, that lack symmetry as adults. However, the larval fish are bilaterally symmetrical. Animals may be characterized by the presence of a coelom, formation of the mouth, and type of cell cleavage during embryonic development.
How are sponges different from most other animals?
Sponges do not have the complex immune systems of most other animals. However, they reject grafts from other species but accept them from other members of their own species. In a few marine species, gray cells play the leading role in rejection of foreign material.
What kind of symmetry does a snail have?
For most animals, the left half of the body is pretty much a mirror image of the right half, at least on the outside. One exception to this bilateral symmetry is found in snails, whose shells spiral to either the right or the left. Click to see full answer.
