Living World
Characteristics of 
Living Organisms
1
Cellular Organization
All living beings are composed of cells - 
the basic structural units of life.
2
Growth & Metabolism
Living organisms grow and perform 
chemical processes catalyzed by 
enzymes.
3
Reproduction & Adaptation
They produce offspring and possess 
genetic mechanisms to survive changing 
environments.
4
Homeostasis & Consciousness
Living beings maintain internal balance 
and respond to external stimuli.

Biodiversity
The diverse forms

Taxonomy
The science of 
classification that 
projects 
relationships 
between 
organisms.

Other Classification Systems
1
Two Kingdom
Carolus Linnaeus classified 
organisms into Animals and Plants.
2
Three Kingdom
Ernst Haeckel added Protista to 
Animals and Plants.
3
Four Kingdom
Copeland's system: Monera, 
Protista, Animals and Plants.
4
Six Kingdom
Carl Woese separated 
Archaebacteria and Eubacteria 
from Monera.
