Classification of Living Organisms

The video tutorial covers the concept of biological classification, tracing its history from Aristotle to modern systems. It explains various classification systems, including two, three, four, five, and six kingdoms, and delves into the characteristics of the kingdom Monera and its sub-kingdoms. The tutorial also discusses the structure and types of bacteria, highlighting their metabolic diversity and ecological roles.

What is the primary purpose of biological classification?

• To study the diet of organisms

• To determine the habitat of organisms

• To group organisms based on shared characteristics

• To identify the age of organisms

• Five Kingdom System

• Three Kingdom System

• Four Kingdom System

• Two Kingdom System

What distinguishes the five kingdom classification proposed by Whittaker?

• It includes only plants and animals

• It focuses on the habitat of organisms
