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-
Now we will take a look at some solved MCQs based on the chapter Diversity in the Living World
MCQs on Diversity in the Living World
1. the Basis of Classification as Per the Five-Kingdom Classification System is
Cell wall structure
Mode of reproduction
2. If the Five-Kingdom System is Followed, in Which Kingdom Would the Archaea and Nitrogen-Fixing Organisms Go?
3. Who Introduced the Phylogenetic System of Classification?
Adolf Engler and Karl Pranti
George Brentham and J.D Hooker
4. Characters of Flowers Are Used as a Parameter of Classification in Case of Classification of Angiosperms. Why?
Because flowers have attractive colors
Because characteristics of flowers are conservative
Because flowers are visible and large
All of the above
5. The Purpose of Classification or Taxonomy is to
Know the history of evolution
Establish the origin of organisms
Facilitate the identification of unknown organisms or species
Identify the difference between plants and animals
6. Characteristics of Which of the Following is Less General as Compared to the Genus?
7. What Does the Taxonomic Classification Refer To?
Classification of species based on the fossil record
list of botanists or zoologists who have worked on the taxonomy of a species or group
a group of senior taxonomists who decide the nomenclature of animals and plants
Stepwise arrangement of all categories for classification of animals and plants
8. One of the Very First Steps of Taxonomy is
9. Nicotiana Sylvestris Flowers Only During Long Days While N.tabacum Flowers Only During Short Days. However, Both of These Can Be Induced to Flower at the Same Time by Changing the Photoperiods and Can Also Be Cross-Fertilized. the Cross of Both the Species of Flowers Produces Self-Fertile Offspring. What is the Best Reason for Considering Nicotiana Sylvestris and N.tabacum as Separate Species
They are reproductively distinct
They cannot interbreed in nature
They are physiologically different
They are distinct morphologically
10. A True Species Consists of a Population That is-
Sharing the same niche
Feeding on the same food
11. Two Different Plants Can Be Conclusively Said to Belong to the Same Species If They-
Have more than 90% the same genes
Can reproduce with each other freely and produce seeds
Have the same number of chromosomes in their heredity
Look similar and have identical metabolites
12. Which of the Following Combinations is Correct for Wheat?
Genus Triticum, family Poaceae, order Poales, Class Dicotyledonae
Genus Triticum, family Poaceae, order Poales, Class Monocotyledonae
Genus Triticum, family Anacardiaceae, order Poales, Class Monocotyledonae
Genus Triticum, family Poaceae, order Sapindales, Class Monocotyledonae
13. Which of the Following Categories Has Real Existence?
14. Which of the Following is Not a Characteristic of the Kingdom Protista?
The organisms are prokaryotic
The organisms are unicellular
The organisms are eukaryotic
The organisms show the presence of cilia
