Hiiii...
Classification helps us in exploring the diversity of life forms.
The major characteristics considered for classifying all organisms into five major kingdoms are :
whether they are made of prokaryotic or eukaryotic cells
whether the cells are living singly or organised into multicellular and thus complex organisms.
whether the cells have a cell-wall and whether they prepare their own food.
All living organisms are divided on the above bases into five kingdoms, namely Monera, Protista, Fungi, Plantae and Animalia.
The classification of life forms is related to their evolution.
Plantae and Animalia are further divided into subdivisions on the basis of increasing complexity of body organisation.
Plants are divided into five groups: Thallophytes, Bryophytes, Pteridophytes, Gymnosperms and Angiosperms.
Animals are divided into ten groups: Porifera, Coelenterata, Platyhelminthes, Nematoda, Annelida, Arthropoda, Mollusca, Echinodermata, Protochordata and Vertebrata.
The binomial nomenclature makes for a uniform way of identification of the vast diversity of life around us.
The binomial nomenclature is made up of two words – a generic name and a specific name.
