Test: Classification of Chordates - Question 2

Given below are two statements: one is labeled as Assertion (A) and the other is labeled as Reason (R).

Assertion (A):

All vertebrates are chordates but all chordates are not vertebrates.

Reason (R):

Notochord is replaced by a vertebral column in the adult vertebrates.

In the light of the above statements, choose the most appropriate answer from the options given below :

Detailed Solution for Test: Classification of Chordates - Question 2

Statement I: All vertebrates are chordates, but all chordates are not vertebrates.

This statement is true, in vertebrate notochord is replaced by a vertebral column. The notochord is present in the embryonic stage and the adult stage, it is replaced by a bony vertebral column. So, all vertebrates are chordates, but all chordates are not vertebrates

Statement II: A notochord is replaced by a vertebral column in adult vertebrates.

This statement is true, the notochord is a cartilaginous rod that is found in the embryonic stage in vertebrates, and later, it gets replaced by a bony vertebral column. That is why they are known as vertebrates.

So, the correct answer is 2.

Test: Classification of Chordates - Question 3

Which one of the following is a matching pair of an animal and a certein phenomenon it exhibits?

Detailed Solution for Test: Classification of Chordates - Question 3

The Musca genus comprises various flies, with Musca domestica, commonly known as the housefly, being one of its members. Houseflies undergo complete metamorphosis, progressing through egg, larva or maggot, pupa, and adult stages. In contrast, Pheretima lacks sexual dimorphism and is hermaphroditic, possessing reproductive organs of both sexes. Chameleons are known for their camouflage, not mimicry. While mimicry involves an animal resembling something obvious but uninteresting or undesirable, camouflage is the act of an animal blending into its surroundings to avoid being easily noticed.

Which one of the following statements is incorrect about the occurrence of notochord? ​

Detailed Solution for Test: Classification of Chordates - Question 13

Humans belong to the phylum Chordata. Animals belonging to the phylum Chordata possess a notochord either during early embryonic life or throughout the embryonic life. In some, it is replaced by vertebral column. In humans, notochord is present only in the embryonic stage, it is replaced by vertebral column in the adult form.

Test: Classification of Chordates - Question 14

In some chordates, the notochord is modified as the vertebral column. Such animals are called vertebrates. Which one of the following statements makes sense?

Detailed Solution for Test: Classification of Chordates - Question 14

Chordates are those animals that have rod-like notochord. Notochord is also present in vertebrates but in most adult vertebrates, the notochord is replaced by vertebral column, which is the peculiar feature of vertebrates. Thus, we can say that all vertebrates are chordates but as chordates are not vertebrates.

Detailed Solution for Test: Classification of Chordates - Question 21

Animals show four different grades of organization, (i) Protoplasmic grade found in protozoans. (ii) cellular grade is the characteristic of sponges and mesozoans because in a sponge, cells exhibit division of labour for performing specialized functions. (iii) Tissue grade is of two types : Cell-tissue grade is seen in coelenterates as there are cells not only specialized for different functions but also certain similar cells gather together to form tissue as well. Tissue - organ grade appears in flatworms (Platyhelminthes) with arrangement of tissues to form organs, (iv) In organ system level of organisation, organs are joined in a system to perform basic functions. It is found in higher invertebrates and all vertebrates.

(i) Body is streamlined and mouth is terminal.
(ii) Gills are covered by operculum.
(iii) Skin covered with cycloid and placoid scales.
(iv) Many of them are viviparous. 

Detailed Solution for Test: Classification of Chordates - Question 30

Osteichthyes is a class of fish that includes bony fish. Some of the characteristics of this class include:

  • Body is streamlined and mouth is terminal: This characteristic is correct and would not be excluded from the list of characteristics of Osteichthyes.

  • Gills are covered by operculum: This characteristic is correct and would not be excluded from the list of characteristics of Osteichthyes.

  • Skin covered with cycloid and placoid scales: This characteristic is incorrect and would be excluded from the list of characteristics of Osteichthyes. Osteichthyes have scales on their skin, but these scales are not necessarily cycloid or placoid.

  • Many of them are viviparous: This characteristic is incorrect and would be excluded from the list of characteristics of Osteichthyes. Many Osteichthyes are oviparous, meaning they lay eggs, rather than being viviparous, meaning they give birth to live young.

Therefore, the correct answer is (iii) and (iv).
