Which of the following are acoelomates?

Well Acoelomates are Porifera, Coelenterates, Ctenophore, Platyhelminthes.

Are most animals acoelomate?

Most bilateral animals, including all the vertebrates, are coelomates. Pseudocoelomate animals have a pseudocoelom (literally “false cavity”), which is a fluid filled body cavity.

Which is an acoelomate animal 2 points?

An acoelomate is an animal which lack a coelom, or formal body cavity. True body cavities form only in multicellular organisms with true tissues. Within this group, the eumetazoa, there are the organisms like coral and jellyfish, which have only 2 basic tissues.

Is hookworm an acoelomate?

Explanation: Liver fluke is a Platyhelminthes and is the acoelomate animal. Hookworm is Ancylostoma, it is an Aschelminthes animal and is pseudocoelomate as their body cavity is Pseudocoelom (fluid filled body cavity present in between the mesoderm and ectoderm). Jellyfish is a Coelenterate animal and is acoelomate.

Which are triploblastic acoelomate animals?

Platyhelminthes phylum was the first one to be triploblastic, that is, they had all the 3 embryonic layers. 2. Platyhelminthes do not have any coelom so they are called acoelomates.

Is porifera an acoelomate?

Yes, animals of the phylum Porifera and Cnidaria are acoelomates. They do not possess a body cavity, which is lined by mesoderm. Also Check: Coelom.

Why are platyhelminthes called acoelomate?

Flatworms are called acoelomate animals. They do not possess a body cavity or coelom Since there is no body cavity in these animals their body is solid without a perivisceral cavity.

Is Mollusca an acoelomate?

Abstract. Molluscs had a common origin with the annelids, as shown by remarkable ontogenetic similarities. Their common ancestors were non-segmented (non-eumetameric), acoelomate animals.

What are acoelomates give an example class 11?

The animals in which body cavity is absent are called acoelomates. Example: Tapeworm, Liver fluke.

Is fasciola an acoelomate?

Answer: (c) The statement, Fasciola is a pseudocoelomate animals, is incorrect as it does not possess body cavity hence, it is an acoelomate. Mesoglea is an undifferentiated layer and is a characteristic of diploblastic and triploblastic animals present along with ectoderm and endoderm.

Which phylum contain acoelomate animals?

Platyhelminthes
The three phyla considered in this chapter are the Platyhelminthes or flatworms; the Nemertea or ribbon worms; and the Gnathostomulida or jaw worms. The following is a list of Acoelomate animal characteristics.

Is Taenia triploblastic acoelomate?

Complete answer: Both Taenia sodium and Fasciola hepatica belong to the phylum Platyhelminthes. The Platyhelminthes type are triploblastic, acoelomate (without body cavity), and bilaterally symmetrical animals. The body is smooth, non-segmented, flat towards the abdomen.

What are examples of coelomates?

Humans and other vertebrate animals are some examples of coelomate animals. Coelomate animals are those whose body structure is based on a body cavity lined on the inside and around the gut by mesoderm.

Are arthropods coelomates?

Coelomates can be found in both protostomes and deuterostomes. Protostomes such as annelids , mollusks, and arthropods are coelomates. Deuterostomes such as Chordata , Echinodermata , Brachiopoda, Ectoprocta, and Phoronida are coelomates. Acoelomates , ceolomates, and pseudocoelomates are shown in figure 2.

Are humans coelomate?

Coelomates are animals that have internal body cavities, or coeloms. Humans are coelomates, we have an abdomenal cavity (digestive organs, some of the excretory and reproductive organs) and a thoracic cavity (heart and lungs). Coelomates also form a variety of internal and external skeletons.
