NCERT Solutions for Class 9 Science Chapter 7 Diversity in Living Organisms

 

NCERT Solutions for Class 9 Science Chapter 7 - Diversity in Living Organisms: Have you ever thought of the multitude of life-forms that surround us? Each organism is different from the other to a lesser or greater extent. For instance, consider yourself and a friend that are you both of the same height? or does your nose look exactly like your friend’s nose? or is your hand-span the same as your friend’s? then, this chapter will give you all the answers to these questions. 

Classification is the most important thing which you will study in this chapter. It helps us in exploring the diversity of life forms. The major characteristics considered for classifying all organisms into five major kingdoms are: 

  • (a) whether they are made of prokaryotic or eukaryotic cells 
  • (b) whether the cells are living singly or organized into multi-cellular and thus complex organisms 
  • (c) whether the cells have a cell-wall and whether they prepare their own food.
