MCQs on Diversity in the Living World

NEET is a prestigious entrance exam for medical which enables the students to apply for medical colleges in the country. The pattern of the exam is objective questions based on chapters from the syllabus. NEET exam is carried out in four sections- Physics, Chemistry, Botany, and Zoology. The total number of questions in the paper is 180 with a total scorable of 720. Half of the total weightage is given to the subject biology that makes 50% of the questions from the subject biology. Moreover, diversity in the living world is the first unit in the biology syllabus. This chapter has good marks weightage in the biology paper and with effective preparation and practice, students can score higher marks in the NEET exam.

Diversity in the Living World for NEET

Our planet is dominated and co inhabited by millions of organisms. Some warmer regions show an exceptionally high diversity of organisms, while some colder regions are a host to only fewer species. The warmer regions with exceptionally high biodiversity are referred to as regions of mega biodiversity. Trillions of years ago, when life just started on Earth, it has only a few forms of life. But, after so many years, organisms have evolved into higher and higher species to survive and continue their existence. Some species have been left behind and have gone extinct but those who have survived are continuously evolving with the changing environments.

Therefore, it is important to group organisms on the basis of their similarities and dissimilarities. The system of classifying living organisms into groups is known as classification. Classification in the living world is done on various parameters. The widely accepted classification system across the world is a five-kingdom classification. The Hierarchy of classification in the five-kingdom system is-

  • Kingdom

  • Phylum

  • Class

  • Order

  • Family

  • Genus

  • Species

Now we will take a look at some solved MCQs based on the chapter Diversity in the Living World
