What do Cnidaria and Porifera have in common?
Porifera and Cnidaria are organisms which share similar characteristics with one another. -They are both multicellular, they consist of many cells working together. They are both eukaryotic, they have DNA in the form of chromosomes contained within a distinct nucleus.
What are examples of Cnidaria and Porifera?
Lesson Summary
- Sponges are aquatic invertebrates in Phylum Porifera. Sponges have specialized cells and an endoskeleton, but they lack tissues and body symmetry.
- Cnidarians are aquatic invertebrates in Phylum Cnidaria. They include jellyfish and corals, both of which have radial symmetry.
What is the difference between phylum Porifera and Cnidaria?
Cnidaria and porifera are two different phyla. Cnidarians have Cnidocytes but not the poriferans. Cnidarians have well-organized organ systems but not the poriferans; on the other hand, poriferans have an efficient tunnel system made up of pores but not the cnidarians.
Why are poriferans and cnidarians considered to be animals?
The sponges and the cnidarians represent the simplest of animals. Sponges appear to represent an early stage of multicellularity in the animal clade. Although they have specialized cells for particular functions, they lack true tissues in which specialized cells are organized into functional groups.
What are the similarities and differences between animals in the phylum Porifera and Coelenterata?
Porifera | Ctenophora |
---|---|
Animals show cellular level of organisation. | Animals show tissue level of organisation. |
They are asymmetrical. | They are radially symmetrical. |
Digestion is intracellular. | Digestion is extracellular and intracellular. |
Fertilisation is internal. | Fertilisation is external. |
What do Porifera Ctenophora and Cnidaria have in common regarding symmetry?
What do Porifera (sponges), Ctenophora (comb jellies) and Cnidaria (jellyfish, corals, anemones, and hydroids) have in common regarding symmetry? They are non-bilaterian.
What characteristic do all cnidarians have in common?
All Cnidaria are aquatic, mostly marine, organisms. They all have tentacles with stinging cells called nematocysts that they use to capture food. Cnidarians only have two body layers, the ectoderm and endoderm, separated by a jelly-like layer called the mesoglea. Most Cnidarians have radial symmetry.
What do Porifera ctenophora and Cnidaria have in common regarding symmetry?
What are the similarities and differences between animals in the phylum porifera and Coelenterata?
How are sponges and cnidarians alike and different?
Sponges have multiple cell types that are geared toward executing various metabolic functions. Cnidarians have outer and inner tissue layers sandwiching a noncellular mesoglea. Cnidarians possess a well-formed digestive system and carry out extracellular digestion.
How is the body plan of a cnidarian similar to that of a sponge?
How is the body plan of a cnidarian similar to that of a sponge? They are both soft bodied animals with a hollow central cavity.
What is common between Porifera and coelenterates?
Porifera and coelenterata are two phyla of kingdom Animalia which include primitive aquatic animals. Both phyla consist of animals living in fresh and marine water.
What are the main differences among Porifera Cnidaria and ctenophora?
Cnidaria and Ctenophora are two types of phyla composed of coelenterates. Cnidarians live in both freshwater and marine habitats while ctenophores only live in the sea. Cnidarians are diversified animals than ctenophores.
What are the unique attributes of sponges and cnidarian?
Which pair of words describes the two common body types of cnidarians?
Two distinct body plans are found in Cnidarians: the polyp or tuliplike “stalk” form and the medusa or “bell” form. ((Figure)). An example of the polyp form is found in the genus Hydra, whereas the most typical form of medusa is found in the group called the “sea jellies” (jellyfish).
How is the body plan of a Cnidarian similar to that of a sponge?
Which body plan of cnidarians is more similar to that of porifera?
Which of the following is common to both sponges and Coelenterate?
Sponges and Coelenterates resemble each other in being diploblastic.
How do Poriferans differ from coelenterate animals?
Was this answer helpful?…How do poriferan animals differ from coelenterate animals.
Poriferan animals | Coelenterate animals |
---|---|
Poriferans are asymmetric and non-motile | Coelenterates are radially symmetrical and motile |
These entities are porous, they have holes throughout their body | These entities have a coelenteron, a body cavity which has only one opening |
What are the differences between the poriferans and cnidarians?
• Cnidarians have well-organized organ systems but not the poriferans; on the other hand, poriferans have an efficient tunnel system made up of pores but not the cnidarians. • Poriferans evolved earlier than cnidarians, according to the fossil evidence.
What are the differences between Cnidaria and other phylums?
Epitheliomuscular cells whose bodies form part of the epithelium but whose bases extend to form muscle fibers in parallel rows.
Do Porifera have a pseudocoelom?
Yes. Aceolmates have no true body cavity. Porifera have no coelom, or a pseudocoelom, a body cavity not lined with mesodermal cells. Whether or not porfiera is an acelomate seems to depend on the source of the information: The acoelomate phyla are Placozoa , Porifera , Cnidaria , Ctenophora , Platyhelminthes, Mesozoa, Nemertina, Gnathostomulida.
What animals live in cnidarians?
cnidarian, also called coelenterate, any member of the phylum Cnidaria (Coelenterata), a group made up of more than 9,000 living species. Mostly marine animals, the cnidarians include the corals, hydras, jellyfish, Portuguese men-of-war, sea anemones, sea pens, sea whips, and sea fans.
