1. The biological classification was attempted instinctively
The first attempt for Biological classification was because of the need to use organisms for our own use. Here which kind of uses are considered?
Food and shelter
Food and Hunting
Food, shelter and clothing
Except clothing all are correct
First time the scientific basis for classification was attempted by -
Theopharastus
Aristotle
Van Neil
Darwin
Which of the following statement is not incorrect with respect to biological classification attempted by Aristotle?
Based on complex morphological characters
Plants were classified into trees, shrubs and herbs
Animals were classified on the basis of nutrition
Phylogeny was also considered
The presence of RBC to classify animals was used as a unique criterion by
Huxley
Which of the following statement is wrong with respect to two Kingdom classification?
Developed at the time of Linnaeus
Used till very recently
Could distinguish between photosynthetic and non-photosynthetic
Easy to do and easy to understand
Which of the following was not the limitation of two Kingdom classification?
Could not distinguish between eukaryotes and prokaryotes
Couldn't distinguish between unicellular and multicellular
Large number of organisms remained unclassified
Very difficult to classify and understand
Which of the following statement is not correct regarding biological classification?
Gross morphology was not considered in two Kingdom classification
Classification system has undergone many changes over the time
Two Kingdoms are constant throughout just the concept of understanding them has been changed
Nature of wall and method of reproduction was the two criteria which were also needed to consider after two kingdom classification.
The five kingdom classification system was given by
1968
1969
1965
1966
Whittaker’s system of classification does not has
Mychota
Protista
Algae
Plantae
Which out of the following was not the basis of the five kingdom classification?
Cell structure
Thallus organization
Phylogenetic Relationship
Gross morphology
If any organism has eukaryotic cells with no cellulose in cell wall and does not form compact tissue or organ level of organization, what kind of kingdom its should belong to (according to Whittaker)?
Fungi
Monera
If an organism is made up of eukaryotic cell with cellular level of body organization, where should it be kept?
Animals
The organism in which cell wall is found and made up of Polysaccharides and amino acid will be grouped under
Animalia
The organism in which organ system level of body organization is found are
Plantae and Animalia
None of the above
The organism with nuclear membrane, cellular level of body plan and autotrophic mode of nutrition can be-
Holozoic mode of nutrition is observed in
