Important Topics for NCERT Exemplar Class 9 Science Solutions Chapter 7: Diversity in Living Organisms

This chapter of NCERT Exemplar covers different topics like living organisms, their types, the classification of organisms, etc. Check below some of the topics discussed in the chapter:

Biodiversity

Biodiversity is known as the variety of living organisms that are present on earth. The earth possesses around 20 lakh organisms that differ in several ways.

Classification

Classification is known as a process in which different organisms are organized on the basis of their similarities and differences.

Classification System

  • Types of Cellular Organization
  • Body organization
  • Mode of Obtaining Food

Important Points to Remember from the Chapter:

  • The classification of organisms is necessary to know the diversity of life forms that is present on earth. 
  • The major identification patterns to classify organisms into 5 kingdoms are:
  1. If they are made of eukaryotic or prokaryotic cells
  2. If the cells are living singly or are organised into multicellular or complex organisms. 
  3. If the cells have cell walls or if they prepare their own food 
  • According to the above-listed points, the organisms are divided into 5 kingdoms that are Protista, Monera, Fungi, Plantae and Animalia. 
  • The Binomial nomenclature is a uniform way that helps in identifying the vast diversity of life around us. 
  • There are five groups of plants: Thallophytes, Bryophytes, Pteridophytes, Gymnosperms, and Angiosperms.
