All the organisms are divided into five kingdoms which are Monera, Protista, Fungi, Plantae and Animilia. The bases for classifying all organisms into five groups are:
(i) Type of cellular organization: whether the organism is prokaryotic or eukaryotic
(ii) Body organization: whether the organism is multicellular or unicellular
(iii) Mode of obtaining food: whether the organism is autotrophic of heterotrophic
(iv) Presence or absence of cell wall
