What is the difference in body symmetry between the Phylum Echinodermata and the Phylum Chordata?
The body of the Phylum Echinodermata is divided into 5 equal sections whereas the body of the Phylum Chordata is divided bilaterally (2 sections).
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?
chordata
What type of symmetry do nematodas have?
The nematodes(members of phylum Nematoda) exhibit bileteral symmetry.
Which type of symmetry do annelids exhibit?
Annelids (such as earthworm and leeches) have bilateral symmetry.
Type of symmetry in which body parts are mirror images of each other?
Bilateral Symmetry
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?
The body of the Phylum Echinodermata is divided into 5 equal sections whereas the body of the Phylum Chordata is divided bilaterally (2 sections).
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.
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?
chordata
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.
What type of symmetry does the phylum Cnidarian have?
Crustaceans, like other crustaceans, have bilateral symmetry. Bilateral symmetry means something has symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
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.
