What is the unifying characteristic of the Opisthokonta?

A common characteristic of opisthokonts is that flagellate cells, such as the sperm of most animals and the spores of the chytrid fungi, propel themselves with a single posterior flagellum. It is this feature that gives the group its name.

What is the defining trait of the supergroup Opisthokonta?

One of the most characteristic features of the Opisthokonta is the architecture of flagellate cell, and this feature is origin of the name ‘Opistho-konta’. Flagellate cell possesses a single flagellum inserted posteriorly. Mitochondrial cristae are usually flat.

What clades are within Opisthokonta?

The Opisthokonta comprise metazoans (animals), fungi and several additional microbial eukaryote lineages, including the Choanoflagellida, Ichthyosporea, Nucleariidae and Capsaspora. It is likely that the closest extant relative of both fungi and metazoans is a member of the Opisthokonta.

How does Opisthokonta reproduce?

Haploid, motile schizonts reproduce by fission. Schizonts act as gametes, fusing to form diploid zygotes.

How are oviraptorosaurs different from other theropods?

… was a primitive member of Oviraptorosauria, a group of theropods that were closely related to birds. Oviraptorosaurs differed from most other theropods in having a deep belly and a short, stiff tail. In addition, many forms had few, if any, teeth.

Which is the best description of the opisthokonts?

The opisthokonts ( Greek: ὀπίσθιος ( opísthios )=”rear, posterior” + κοντός ( kontós )=”pole” i.e. ” flagellum “) are a broad group of eukaryotes, including both the animal and fungus kingdoms. The opisthokonts, previously called the “Fungi/Metazoa group”, are generally recognized as a clade.

Where did the Oviraptor get its name from?

The nomenclature of the group represents the initial theory that the creatures’ diet consisted of eggs stolen from other dinosaurs’ nesting areas, but this theory is no longer considered valid. Oviraptor remains were discovered in Mongolia on top of a nest, which led many to speculate that the creatures were egg raiders.

How are Holozoa and Opisthokonts related?

More recently, it has been said that holozoa (animals) and holomycota (fungi) are much more closely related to each other than either is to plants, because opisthokonts have a triple fusion of carbamoyl phosphate synthetase, dihydroorotase, and aspartate carbamoyltransferase that is not present in plants,…
