What are the 5 characteristics of chordates?

The five characteristic features of chordates present during some time of their life cycles are a notochord, a dorsal hollow tubular nerve cord, pharyngeal slits, endostyle/thyroid gland, and a post-anal tail.

Why are Urochordates called tunicates?

The name tunicates comes from the tunic surrounding their body. The name sea squirt comes from the way water is pushed out through the exhalant siphon. … On the inside of the epidermis is a thicker dermis (body wall) and bands of muscles which can squeeze the tunic forcing a jet of water from the exhalant siphon.

What are the advantages of biological classification?

The advantages of classifying organisms are as follows: (i) Classification facilitates the identification of organisms. (ii) helps to establish the relationship among various groups of organisms. (iii) helps to study the phylogeny and evolutionary history of organisms.

Is Protochordata a phylum?

Protochordates are an informal category of animals (i.e.: not a proper taxonomic group), named mainly for convenience to describe invertebrate animals that are closely related to vertebrates. This group is composed of the Phylum Hemichordata and the Subphyla Urochordata and Cephalochordata.

What is classification what is the need for classification What is the basis of classification?

According to his system of classification, he grouped organisms according to common physical traits and developed the two-part binomial taxonomy system of categorizing organisms according to genus and species. This type of classification was effective.

What is classification and types?

Organisms can be classified on the basis of several different factors. According to this, the different factors include the nature of the cell; the mode of nutrition seen in organisms and also based on the body organization. Broadly, the following are the different types of classification.

What is called biological classification?

Classification, in biology, the establishment of a hierarchical system of categories on the basis of presumed natural relationships among organisms. The science of biological classification is commonly called taxonomy (q.v.).
