The Living World

Hello!

These are the important points on The Living World. 

Living organisms are self replicating, evolving and self regulating, interactive systems capable of responding to external stimuli. 


Metabolism, cellular organisation and consciousness are the defining characteristics of living things. While growth and reproduction are important characteristics but not defining characteristics of living things. 


Taxonomy includes the rules and principles for identification, nomenclature and classification of organisms. 


Binomial nomenclature is the most convenient and the most popular system. It was given by Carolus Linnaeus. 


The main taxonomic categories are: Kingdom, phylum or division, class, order, family, genus and species.


The taxonomical aids are: 

Herbarium, botanical gardens, museum, zoological parks and key.
