Diversity in Living World MCQ for NEET

To understand about the topic and Diversity in the Living World NEET questions, let’s go through this article. Students will definitely attain a greater understanding of the subject and get some ideas for the NEET question on living world diversity.

What is the Meaning of Diversity in the Living World?

To get all the answers correct for diversity in the living world NEET questions, we should know what the topic is all about. First we should know diversity means unique and different and without diversity, it is definitely boring. Under this chapter for NEET papers, the description of multiple diverse living organisms from the perspective of taxonomy are covered.

This includes the description about classification, attributes, properties and exceptional features of living organisms. Students will gain concepts that can be applied in other chapters such as structural organization in plants and animals and reproduction. Therefore, it is important for students to well comprehend the chapters in the Unit Diversity in the living world. All examples, features and major points of this topic should be well known and thus preparations are must. After knowing all these, one can handle any diversity in the living world NEET questions and answers. 

Let’s Get a Brief Idea on What Topics are Covered in the Diversity in Living World MCQs for NEET.

1. The Living World: It covers the features of living organisms such as metabolism, hierarchy of taxonomic classification and taxonomical aids. Hierarchy of biological classification is as follows: 

• Kingdom

• Phylum

• Class

• Order

• Family

• Genus 

• Species

2.Biological Classification: Students will be well known with the diverse living organisms. The five kingdom classification proposed by R.H Whittaker is the focus of this chapter and the three kingdoms covered in the biological classification are:

• Kingdom Protista: It is about the eukaryotic cellular organization and students will know about chrysophytes, dinoflagellates, euglenoids, protozoans and slime molds.

• Kingdom Monera: It is the world of bacteria and one can know about the prokaryotic organization of cells, types and different forms of nutrition of bacteria, etc. As per the NEET point of view, students should prepare well about archaebacteria, eubacteria, mycoplasma and cyanobacteria. 

• Kingdom Fungi: It will cover the ubiquitous fungal forms, their types, their mode of nutrition and the mode of reproduction. Different classes of kingdom fungi based on their reproduction, hyphae and fruiting bodies.

• Other categories of living organisms such as viroids, prions, lichens and viruses can also be understood in this chapter, their classification and diseases caused by them can be known.

3. Plant Kingdom: This is the fourth kingdom from where students can expect a lot of questions in the NEET MCQs besides the other kingdoms. It makes you understand about the autotrophic or heterotrophic mode of nutrition. The divisions of this kingdom include Thallophyta, Bryophyta, Pteridophyta, Gymnosperms and Angiosperms.

4. Animal Kingdom: This classification by Whittaker comprises very fascinating animals and students can gain information about the body organization, body symmetries, notochord, coelom, etc. Invertebrate and Vertebrates are the two categories based on the notochord. Different Phyla are covered in this section which are as follows:

• Phylum Porifera

• Phylum Coelenterata

• Phylum Ctenophora 

• Phylum Platyhelminthes

• Phylum Aschelminthes

• Phylum Annelida

• Phylum Arthropoda

• Phylum Mollusca

• Phylum Echinodermata

• Phylum Hemichordata

• Phylum Chordata

More about Diversity in the Living World

Diversity in the Living World is the important unit in the NEET Biology Syllabus and it helps in creating the foundation of fundamental classifications and understanding. The concepts are necessary that enable progress on much broader concepts later on in other units. Different types of living beings are found in various sorts of living spaces like sea, Freshwater Bodies, Backwoods, Cool Mountains, Deserts, Warm Water Springs and so on. It is because the answer requires separating the living and the non-living. It is estimated that more than 5 millions species are available on earth. Each and every organism of this living world whether they are plants, animals, bacterias, and viruses, they all are unique in some way or other and it is because of the diversity in the living organisms. The diversity is important because it helps to identify various living organisms around the world and students can learn about them all. Diversity of living organisms is important because it helps to understand the interrelation among different groups of organisms and also it helps in the development of biological science. Diversity of living organisms can be classified into four types : The Living world, Biological Classification, Plant Kingdom, and Animal kingdom.

• The Living World : Diversity in Living World is classified as : Kingdom, Phylum, Class, Order, Family, Genus, and Species.

• Biological Classification : Diversity in Biological Classification is classified as : Kingdom Monera, Kingdom Protista, and Kingdom Fungi.

• Plant Kingdom : Diversity in Plant Kingdom is classified as : Thallophyta, Bryophyta, Pteridophyta, Gymnosperms, and Angiosperms.

• Animal Kingdom : Diversity in Animal Kingdom is classified as : Phylum Porifera, Phylum Coelenterata, Phylum Ctenophora, Phylum Platyhelminthes, Phylum Aschelminthes, Phylum Annelida, Phylum Arthropoda, Phylum Mollusca, Phylum Echinodermata, Phylum Hemichordata, and Phylum Chordata.
