What is incorrect for taxonomic hierarchy?

 

  • 1 There re 7 obligate and more than 21 intermediate categories

  • 2 Higher the category, fewer the numer of organism

  • 3 Lower the ategory, more the number of common features

Genus represents aggregate of closely related species. Which of the following group of species does not belong to same genus?

  • 2 Brinjal, makoi

  • 3 Lion, Leopard

  • 4 Potato, Sweet potato

Both the words in a biological name when handwritten are underlined or printed in italics to indicate :-
  • They are endangered

  • They are living

  • Their latin origin

  • Now they are extinct

Choose the correct from the followings:- 

  • Mangifera, is a name of species

  • Polymoniales, is a name of family

  • Dicotyledonae, is a name of division

  • Triticum, is a name of genus

How many of the following are correct match ?

a. Biodiversity - Number and type of organisms present on earth.

b. Nomenclature - Standardise the naming of living organism 

c. Biological names - Generally in Latin and written in Greek

d. Classification - Classified into different taxa 

  • Four

  • Three

  • Two

  • One 

The correct definition of the genus may be:-

  • Genus is an aggregate of distantly related species

  • Genus is a group of species present in a given area

  • Genus is an aggregate of closely related species

  • Genus is a group species present in a common habitat

Reproduction is a character of living organism but it cannot be regarded as defining property because:-

  • Sexual reproduction involves only a single parent

  • Lower organism do not reproduce under stressful environment

  • All living beings do not have the capacity to reproduce

  • For lower plants, growth and reproduction are mutually inseparable phenomenon

The highest category in the taxonomic hierarchy is

  • Kingdom

  • Phylum

  • Class

  • Species

The system of the naming of organisms was developed by

  • Robert Hooke

  • Carolus Linnaeus

  • T. Schwann

  • Ernst Mayr

Read the statements carefully and select the correct
option:
A. Intrinsic increase in mass of body is defining
property of living organisms.

B. Reproduction is synonymous with growth in
all the organisms

C. Reproduction is defining feature of all
organisms

D. Isolated metabolic reactions in-vitro are living
reactions.

Options:

  • A and B

  • B and C

  • A and D

  • B and D

Taxa with least number of common characteristics are

  • Felis and Panthera

  • Potato, Brinjal and Makoi

  • Polymoniales and Poales

  • Arthropoda and Angiosperms

Which of the given is not a defining property of living organisms?

  • Growth

  • Metabolism

  • Cellular organization

  • Consciousness

The total number and types of organisms on earth represents the

  • Taxonomy

  • Biodiversity

  • Classification

  • Systematics

Which one of the following aspects is an
exclusive characteristic of living things?
both on surface as well as internally
environment and their memory
  • Increase in mass by accumulation of material
  • Isolated metabolic reactions occur in vitro
  • Increase in mass from outside only
  • Perception of events happening in the

Practical purpose of taxonomy or classification :

  • Facilitate the identification of unknown species
  •   Explain the origin of organisms
  •   To know the evolutionary history
  •   Identification of medicinal plants

Which arrangement is in correct ascending order:

  •   Species < genus < order < family
  •   Genus < species < family < order
  •   Order < family < genus < species
  •   Species < genus < family < order

Biosystematics aims at : -

  • The classification of organisms based on broad morphological characters

  • Delimiting various taxa of organism and establishing their relationships

  • The classification of organisms based on their evolutionary history and establishing their phylogeny on the totality of various parameters from all fields of studies

  • Identification and arrangement of organisms on the basis of cytological characteristics

Species are considered as :-

  • Real basic units of classification

  • The lowest units of classification

  • Artificial concept of human mind which cannot be defined in absolute terms

  • Real units of classification devised by taxonomists

Which of the following less general in characters as compared to genus : -

  •   Species
  •   Division
  •   Class
  •   Family

  • Class
  • Phylum
  • Family
  • Kingdom

IV. Consciousness
 
  • I and II
  • I and III

  • II and IV
Monkey, gorilla, gibbon, tiger, cat and dog do not belong to the same:
  • Phylum
  • Order
  • Class
  • Kingdom
Which of the following statement regarding the characteristic and defining features of life is true?
  • When it comes to multicellular organisms, reproduction is synonymous with growth
  • Isolated metabolic reactions in vivo are not living things but living reactions
  • Cellular organisation and consciousness are the defining features of living organisms
  • In majority of the higher animals and plants, growth and reproduction are mutually inclusive events
The branch of biology that deals with the relationships of different groups of organisms and examines their natural variation and relationships is known as:
  • Cladistics
  • Systematics
  • Taxonomy
  • Identification
