What Do You Mean By The Diversity in The Living World?
Notes of Biology Class 11 Chapter 1 let you understand the diversity in the living world thoroughly.
Biodiversity is one of the key features of the different organisms present on earth.
To identify a similar class of living organisms by a similar name a unique procedure has been followed. The procedure is known as nomenclature.
A universally accepted principle is followed by the biologists to give scientific names to known organisms, as you will know from Biology Class 11 notes Chapter 1. Every name is classified into two components – the generic name and the specific epithet. This procedure of giving names with two components is known as Binomial Nomenclature.
Classification is the process of studying all the living organisms.
The scientific term for studying the various categories of living organisms is known as taxa.
Each and every living organism can be divided into different taxa. The procedure of classification is known as taxonomy.
The study of the relationship between the various kinds of organisms and their diversities is known as systematic according to NCERT Class 11 Biology Chapter 1 notes.
What are the Taxonomic Categories?
Classification, as Class 11 Biology NCERT notes Chapter 1 will tell you, is not a single step procedure only. It involves various steps. Each and every step represents a rank or category. The category is defined as a taxonomic category.
