Solution 2

The method of arranging organisms into series of groups on the basis of similarities and differences is called classification.
Classification is important in the following ways:
(i) It makes the study of a wide variety of organisms easy.
(ii) It gives us an overall picture of all the life-forms.
(iii) It helps us to understand the interrelationships among different groups of organisms.
(iv) It forms a base for the development of other biological sciences.

Solution 4

Taxonomy is the study of the theory, practice and rules of classification of living and extinct organisms.

Solution 5

The five kingdom system of classification was proposed by R. H. Whittaker in 1969. This classification is based on the following four facts:
