H. Whittaker in 1969. This classification is based on the following four facts:<\/p>\n<ul>\n<li>Complexity of cell structure<\/li>\n<li>\u00a0Methods of nutrition (autotrophic or heterotrophic)<\/li>\n<li>Complexity of body organization.<\/li>\n<li>\u00a0Phylogenetic relationships.<\/li>\n<\/ul>\n<p>The five kingdoms in this system are:<\/p>\n<ol>\n<li><strong>Monera &#8211;<\/strong> It includes all the prokaryotes like bacteria and cyanobacteria. They are important decomposers.<\/li>\n<li><strong>\u00a0Protista &#8211;<\/strong> It includes the aquatic, eukaryotic, acellular organisms like protozoans.<\/li>\n<li><strong>Fungi<\/strong> &#8211; This kingdom includes moulds, mushrooms and yeasts.<\/li>\n<li><strong>Plantae<\/strong> &#8211; It includes all the coloured, multicellular, eukaryotes with cell

are:<\/strong><\/p>\n<ol>\n<li>It contains acellular organisms, ranging in size between 0.15\u00a0 to 2.0 .<\/li>\n<li>\u00a0They are prokaryotes, lacking a well-defined nucleus .<\/li>\n<li>They usually lack chlorophyll and hence are parasites or saprophytes.<\/li>\n<li>Reproduction occurs by binary fission or budding in bacteria.<br \/>\nExample &#8211; Actinomycetes, bacteria, cyanobacteria.<\/li>\n<\/ol>\n<p><strong>Characters of kingdom Protista are:<\/strong><\/p>\n<ol>\n<li>\u00a0They are aquatic, unicellular organisms.<\/li>\n<li>They have eukaryotic cells with well-defined nucleus and organelles.<\/li>\n<li>They show autotrophic or heterotrophic mode of nutrition.<\/li>\n<li>Some protists are parasites and few are decomposers too.<br \/>\n<strong>Example &#8211;<\/strong> Euglena, Ameoba, Paramoecium.<\/li>\n<\/ol>\n<p><strong>\u00a0Characters of kingdom Fungi:<\/strong><\/p>\n<ol>\n<li>\u00a0They may be unicellular or multicellular.<\/li>\n<li>They
