Globally, the humid and warm regions of the earth are regarded as having a great diversity of life. Class 11 of the biology syllabus begins with a study of diversity in the living world. The chapter carries a lot of weight. The taxonomy provides you with insights into the diverse living organisms that inhabit the Earth. Living organisms will be explained in detail, along with their classification, properties, attributes, and exceptional characteristics. Each person has a different DNA sequence. The characteristics of species may vary widely. Further, the concepts covered in this chapter will help the student comprehend upcoming biology chapters. Therefore, it is imperative that students are familiar with this chapter's concepts and theories.
National Eligibility Entrance Test(NEET)
Medical colleges in India accept NEET as an entry requirement for their applicants. The examination is divided into objective questions based on sections of the syllabus. Physics, Chemistry, Botany, and Zoology are the four sections of the NEET. The paper has a total of 180 questions and a total score of 720. A total of 50% of the questions are from the subject biology as it receives half of the weighting. The biology syllabus is also divided into first and second units that deal with diversity in the living world. With good preparation and practice, students can score high marks on the biology paper. This chapter has good marks in the biology paper.
Diversity in the Living World
A vast number of organisms share our planet with us and dominate it. The diversity of organisms in warmer regions tends to be exceptional, while in colder regions only a few species live. A region of mega biodiversity is one when it has exceptionally high levels of biodiversity despite being warm. When life began on Earth billions of years ago, there were just a few forms of life. In the long period of time since organisms have evolved into higher and higher species, they have managed to survive and continue to exist. Many species have gone extinct due to the changing environments, but those who have survived have continued to evolve.
Classification of Living Organisms
Due to the diversity, it is important to group organisms based on what these organisms have in common and what they don't have in common. This process of organizing living organisms into distinct groups is called classification. Various parameters are taken into account when classifying living organisms. Five-kingdom classifications are commonly accepted around the world. There are five levels of classification in the five-kingdom system.
The Necessity of Studying Diversity in the Living World
This contains descriptions of the classification, attributes, properties, and exceptional features of living organisms. In addition to learning about biological structures, students will gain knowledge about the reproduction and structural organization of animals and plants. Therefore, it is important that students have a solid understanding of the chapters of the unit Diversity In The Living World. Preparation is imperative for this topic because all examples, features, and important points need to be well known. NEET questions in today's world will be diverse, but if one knows all these, they will be easy to deal with.
Look at some solved MCQs based on the chapter diversity in the living world, which are available in a PDF on the Vedantu app or Vedantu website.
MCQs on Diversity in the Living World
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
