But Carolus Linnaeus later divided all living organisms into two categories or kingdoms namely Plantae and Animalia.<\/span><\/p>\n<p><span style=\"font-weight: 400\">The two-kingdom classification did not work long as it did not consider all the factors while dividing. As a result, scientists started working on the model again. The five-kingdom classification of plants and animals of 1969 is a proposal by R.H. Whittaker.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">This elaborate division looks at five kingdoms &#8211; Monera, Protista, Fungi, Plantae, and Animalia. The division is on the basis of distinctive features of different living organisms. Some of the criteria are the structure of the cell, organization of the body, nutrition and reproduction process, and more.<\/span><\/p>\n<p><span style=\"font-weight: 400\">This is one of the basic topics of biology. Classification is nothing but a system of organizing the organism in different categories according to their similarities and differences.

These organisms are prokaryotes, they don\u2019t have a well-defined nucleus but bacterias have a cell wall. This cell wall is made up of amino acids and polysaccharides.<\/span><\/p>\n<p><span style=\"font-weight: 400\">They are microscopic in physical nature. They can be heterotrophic and autotrophic. These microorganisms live in extreme conditions and are abundant.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">The nutrition of these organisms can be by synthesizing their own food, getting it from the environment, or by living on other organisms as parasites. Thus they can be autotrophic or heterotrophic. Some well-known bacteria are blue-green algae and mycoplasma.<\/span><\/p>\n<p><span style=\"font-weight: 400\">These bacterias mainly reproduce by fission.

The virus can cause problems like smallpox and AIDS.<\/span><\/p>\n<p><span style=\"font-weight: 400\">The symptoms in plants are the presence of mosaic, leaf rolling, and yellow leaves with slow growth.\u00a0<\/span><\/p>\n<p><b>Viroids <\/b><span style=\"font-weight: 400\">are smaller than viruses but cause infection. They are RNA-free and don&#8217;t have a protein coat thus are viroid. The RNA is low in molecular weight. They are famous for causing potato spindle tuber disease. <\/span><b>Lichens <\/b><span style=\"font-weight: 400\">live in a symbiotic relationship.<\/span><\/p>\n<p><span style=\"font-weight: 400\">They are usually with algae or fungi. The algal part is autotrophic while the fungal part is heterotrophic. Algae take care of food production while the fungus manages the minerals and vitamins. It is hard to identify both the organisms in lichens. They are best to find non-polluted areas as they only grow there.\u00a0<\/span><\/p>\n<h2>Conclusion<\/h2>\n<p><span style=\"font-weight: 400\">This article covered the five kingdom classification of plants and animals by R.H. Whittaker. It covered all the five kingdoms with details of every aspect. This is a biology article for UPSC which aspirants can read to understand the basic idea behind the model.<\/span><\/p>\n<p><span style=\"font-weight: 400\">It is the most prominent model used to classify organisms when it comes to research and development. It is easy to understand and even the newcomers of the science field can refer to this.<\/span><\/p>\n<p><span style=\"font-weight: 400\">If you are planning to appear for the UPSC exam then you must give it a read. Because it is basic 10th class biology, aspirants can expect this topic in UPSC Prelims as well.\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Aristotle took the initiative to propose the biological classification of plants and animals by identifying simple morphological features.
