CBSE NCERT Class 9 Science Chapter 7: Chapter Summary

In Class 9, Science is considered one of the essential subjects to help build foundations for higher classes. To secure good marks in CBSE Class 9 Science exam, students must read the whole chapter and go through the important highlights of NCERT Class 9 Science Chapter 7.

  • Classification helps us in exploring the diversity of life forms. 
  • The major characteristics considered for classifying all organisms into five major kingdoms are:
    1. Whether they are made of prokaryotic or eukaryotic cells.
    2. Whether the cells are living singly or organised into multi-cellular and thus complex organisms.
    3. Whether the cells have a cell-wall and whether they prepare their own food.
  • All living organisms are divided on the above bases into five kingdoms, namely Monera, Protista, Fungi, Plantae and Animalia.
  • The classification of life forms is related to their evolution.
  • Plantae and Animalia are further divided into subdivisions on the basis of increasing complexity of body organisation. 
  • Plants are divided into five groups: Thallophytes, Bryophytes, Pteridophytes, Gymnosperms and Angiosperms.
  • Animals are divided into ten groups: Porifera, Coelenterata, Platyhelminthes, Nematoda, Annelida, Arthropoda, Mollusca, Echinodermata, Protochordata and Vertebrata.
  • The binomial nomenclature makes for a uniform way of identification of the vast diversity of life around us.
  • The binomial nomenclature is made up of two words – a generic name and a specific name.
