QUESTION: 1

The prime source of taxonomic studies is

Solution:
  • All the living organisms are classified and placed in different taxa based on the different characters of living organisms. This is called taxonomy. Basic concepts of taxonomy are identification, characterization, and nomenclature.
  • Taxonomic studies of various species of plants, animals, and other organisms are useful in agriculture, forestry, industry, and knowing information about our bio reserves and their diversity.
  • Correct classification and identification are required for these studies. The collection of actual specimens of plants and animal species is the essential and prime source of taxonomic studies.

Hence, the Correct Answer is C

QUESTION: 2

All living organisms are linked to one another because ______ .

Solution:
  • All organisms share common genetic material, i.e., DNA and RNA. However, it can vary to certain degrees.
  • In fact, the whole theory of evolution is based on the similarity of genetic materials which indicates common ancestry for living organisms. Variations in the similarity of genetic material give biodiversity which we see all around us.

Hence, the Correct Answer is B

QUESTION: 3

Information on any one taxon can be taken out by

Solution:
  • Monographs contain information on any one taxon. 
  • The monograph represents the detailed study of the organism including its important characters that were used to classify it.
  • This is used for identification purposes as well as to study various aspects of the organism.
  • It is a detailed comprehensive study that relies on the given taxon or taxonomic group.
  • A catalogue is a list of things or data kept or stored in a single book or object. It can be a list of anything, arranged in some order, and when you list things, you catalogue them.
  • Flora is a taxonomical aid which maintains an account of exact habitat and distribution of plants of the particular given area.
  • Flora helps in the correct identification of plants.
  • Manuals are the taxonomic aid which maintains the information for identification of names of species found in an area.

Hence, the Correct Answer is A

QUESTION: 4

The scientific name of mango is written as Mangifera indica L. Pickup the correct statement about the significance of the letter 'L'.

Solution:

Carl Linnaeus was a Swedish botanist, physician and zoologist, who laid the foundations for the modern biological naming scheme of biological nomenclature. He is known as the father of taxonomy and is also considered one of the fathers of modern ecology. In botany, the author abbreviation used to indicate Linnaeus as the authority for the species name. In older publications, sometimes the abbreviation "Linn" is found.

Hence, the Correct Answer is C

QUESTION: 5

As we go from species to kingdom in a taxonomic hierarchy, the number of common characteristics:

Solution:
  • As we go higher from species to kingdom, the number of common characteristics goes on decreasing.
  • Lower the taxa, more are the characteristics that the members within the taxon share.
  • Higher the category, greater is the difficulty of determining the relationship to other taxa at the same level.

Hence, the Correct Answer is C

QUESTION: 6

Museums preserve larger animals and birds ________

QUESTION: 7

The correct sequence of taxonomic categories is _________________.

Solution:

Taxonomic classification is a multi-step process, these taxons are in order and hence also called taxonomic hierarchy. It depends upon the characteristics of the organisms and includes their similarities and differences in them.

  • Species: This taxonomic category contains a group of individuals that have common fundamental similarities. Species can be distinct from one another by morphological differences.
  • Genus: This taxonomic classification contains a group of related species. These species have a few common characters among themselves. For example, the genus Felis includes all cats. The genus Panthera includes P.tigris, P.pardus, P.leo; these are tiger, leopard, and lion respectively.
  • Family: This taxonomic category contains a group of related genera; in plants, families are divided into two categories: vegetative and reproductive structures. In animals, they are based on physical similarities between two genera, which are fewer than at the species and genus level. For example, house cats and lions both belong to the Felidae family, and dogs and wolves both belong to the Canidae family.
  • Order: This taxonomic category has a group of related families, these are identified based on aggregated characters. Families that exhibit similar characters are placed under a single order. Felidae and Canidae both come under the order Carnivora.
  • Class: This taxonomic category comprises related orders. The class Mammalia includes Primata and Carnivora which are composed of monkeys, humans, gorillas, gibbons, and tiger dogs, cats, and wolves. The class Mammalia has many more orders on it.
  • Phylum: This taxonomic category comprises many classes. These phyla are classified on the basis of fundamental features like the presence of the notochord and are classified under phylum Chordata.
  • Kingdom: This is the highest taxonomic classification and consists of many phyla. The Kingdom Animalia consists of all heterotrophic multicellular eukaryotic animals.

Hence, the Correct Answer is D

QUESTION: 8

The taxon 'family' ends with

Solution:

In fungal, algal, and botanical nomenclature, the family names of plants, fungi, and algae end with the suffix "-ceae".
