Study of diversity of organisms and evolutionary relationship amongst them on the basis of all possible characters is called as
1 Txonomy
2 Systematics
3 Alpha-taxonomy
4 Phylogeny
Which statements is incorrect w.r.t. genus?
1 Ech genus may have one or more than one specific epithets
2 It comprises a group of related species
3 It has more haracters in common in comparison to species of other genera
4 Potato an brinjal belong to different genus
Choose the wrong statements w.r.t. distinguishing characteristics of living beings
1 In mjority of higher, the growth and reproduction are mutually exclusive events
2 Degrowth will occur when cataolism exceeds anabolism
3 Isolated metaboli relations in-vitro are neither living things nor living reactions
4 Growth cannot be taken as a efining property of living organisms if we take increase in body mass as a criterion on growth
Select incorrect statements w.r.t. living beings
1 Growth cnnot be taken as a defining property of living organisms
2 Growth can e easily observed in vitro culture
3 Metaboli reactions cannot be demonstrated outside the body in cell-free system
4 All organisms, from the prokaryotes to the most complex eukaryotes can sense an respond to environmental cues
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
4 Greatest similarity in structure is foun in between members of a species
Genus represents aggregate of closely related species. Which of the following group of species does not belong to same genus?
1 Potto, Brinjal
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 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 correctoption:A. Intrinsic increase in mass of body is definingproperty of living organisms.
B. Reproduction is synonymous with growth inall the organisms
C. Reproduction is defining feature of allorganisms
D. Isolated metabolic reactions in-vitro are livingreactions.
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
Select the incorrect match w.r.t. the given taxonomic categories of wheat.
Genus - Triticum
Family - aestivum
Order- Poales
Class - Monocotyledonae
The total number and types of organisms on earth represents the
Taxonomy
Biodiversity
Classification
Systematics
Which one of the following aspects is anexclusive characteristic of living things?both on surface as well as internallyenvironment and their memory
Practical purpose of taxonomy or classification :
Which arrangement is in correct ascending 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 : -
Which one of the following belongs to the family Muscidae?
Cockroach
House fly
Fire fly
Grasshopper
