1. The biological classification was attempted instinctively

  • . to make scientific studies easy
  • . to use organisms for our own use
  • . to make better understanding of the research running in all over the world
  • . to make connection between living and non-living

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

  • Aristotle

  • Theopharastus

  • Van Neil

  • 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.
