Sponges belong to the phylum Porifera and exhibit no body symmetry. Their bodies lack definite shape and are composed of specialized cells organized in a loose aggregation. Sponges are the simplest multicellular organisms and showcase a unique form of asymmetry in the animal kingdom.

What is the difference in body symmetry between the Phylum Echinodermata and the Phylum Chordata?
Echinoderms exhibit pentaradial symmetry, with body parts arranged in multiples of five around a central axis. Chordates, on the other hand, display bilateral symmetry, with a distinct left and right side mirroring each other.
If an unknown organism has bilateral symmetry and a long slender and smooth worm-like body that is not segmented into which phylum can it be classified?
The organism can be classified into the phylum Platyhelminthes, which includes flatworms like tapeworms and flukes. These organisms exhibit bilateral symmetry and have long, slender, worm-like bodies that are not segmented.
Which type of symmetry do annelids exhibit?
Annelids exhibit bilateral symmetry, where the body can be divided into two equal halves along a single plane. This symmetry allows for streamlined movement and sensory coordination in these segmented worms.
What phylum has three germ layers?
The phylum that has three germ layers is the Chordata phylum. This phylum includes animals with bilateral symmetry and a notochord, which gives rise to the three germ layers (ectoderm, mesoderm, and endoderm) during embryonic development. Examples of Chordata include vertebrates like mammals, birds, reptiles, amphibians, and fish.
What type of symmetry do nematodas have?
Nematodes have bilateral symmetry, meaning that they can be divided into two roughly equal halves along a single plane. This symmetry helps to optimize their interactions with their environment and improve their mobility.
What type of body symmetry do the animals in mollu sks phylum have?
Most animals in the Mollusk phylum have bilateral symmetry, where their body can be divided into two equal halves along a single plane. This symmetry allows for more efficient movement and sensory abilities.
What is the difference in body symmetry between the Phylum Echinodermata and the Phylum Chordata?
Echinoderms exhibit pentaradial symmetry, with body parts arranged in multiples of five around a central axis. Chordates, on the other hand, display bilateral symmetry, with a distinct left and right side mirroring each other.
Phylum name for planarian?
The phylum name for planarians is Platyhelminthes, which includes flatworms like the planarian. They are characterized by their flattened body shape and bilateral symmetry.
What type of symmetry do phylum porifera have?
Phylum Porifera sponges have radial symmetry.
Do Cnidarians have radial symmetry and tissues to carry out body functions?
Yes. They are are the first phylum to display cell organization into tissues and the second to desplay radial symmetry.
What type of animal has no symmetry?
Actually all Cnidarians have radial symmetry (able to be divided into identical pie-shaped segments) and have stinging cells. The invertebrate with no symmetry is probably a sponge, phylum Porifera.
What phylum has radial symmetry as adult?
The phylum Echinodermata has radial symmetry as adults. These organisms include sea stars, sea urchins, and sand dollars, among others. Radial symmetry means that body parts are arranged around a central axis, like the spokes of a wheel.
Echinoderms body description?
Echinoderms are a phylum with usually 5 fold symmetry, spines and calcium carbonate plates.
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.
Bilateral symmetry is characteristic of?
Bilateral symmetry is characteristic of most animals, including insects, mammals, fish, and birds. It refers to the body being divided into two halves that mirror each other, with organisms having a right and left side that are roughly equal. This type of symmetry is advantageous for efficient movement and navigation in their environment.
What is the only animal phylum that does not have tissues and symmetry?
The phylum Porifera (sponges) is the only animal phylum that lacks true tissues and symmetry. Sponges are simple multicellular organisms with specialized cells, but they do not have tissues that are organized into distinct structures like other animals. Additionally, sponges exhibit asymmetry rather than bilateral or radial symmetry found in other phyla.
In which phylum of marine animals did symmetrical body plans first evolve?
Symmetrical body plans first evolved in the phylum Cnidaria. Cnidarians include jellyfish, sea anemones, and corals, and many of them have radial symmetry. This means that their bodies are organized around a central axis, allowing them to have multiple planes of symmetry.
