Test: Biological Classification - October 1, 2022 - NEET MCQ

Aristotle classified the organisms based on their morphological characteristics. His classification neglected characteristics like nature of the cell wall, evolutionary relationships and method of reproduction.

Aristotle classified plants based on their size into herbs (Wheat, Paddy, etc.), shrubs (Rose, Jasmine, etc.) and trees (Banyan, Banana, etc.). He classified animals based on their blood.

Aristotle’s classification contained two kingdoms i.e. Plants and Animals. Plants are sub-divided into herbs, shrubs and tree. Animals are further sub-divided into red blooded and non- red blooded animals.

Aristotle classified the organisms into Plants and Animals whereas Carolus Linnaeus classified the organisms into Plantae and Animalia. Whittaker’s 5 kingdom classification contained Monera, Protista, Fungi, Plantae and Animalia.

Linnaeus and Aristotle’s classification is based on the morphological characteristics of the plants and animals. This classification resulted in classification of organisms like fungi and humans that completely different in the same group.

Linnaeus classified amoeba under Animalia. His classification didn’t consider cell structure, nature of the cell wall, mode of reproduction, evolutionary relationships which resulted amoeba in Animalia.

Aristotle classified organisms as Plants and Animals. He considered Chlorella under the category of Plants. His classification didn’t consider structure of the cell which resulted in Chlorella under Plants in his classification.

In Whittaker’s 5 kingdom classification, all the prokaryotic organisms are grouped under Monera; all the unicellular organisms under Protista and all the fungi form a separate Kingdom. So, Whittaker’s 5 kingdom classification managed to include characteristics like nature and structure of cells.

In Whittaker’s 5 kingdom classification, all the unicellular organisms are categorised under Protista. For example, Amoeba, Paramecium, Chlorella and Chlamydomanas fall under the category of Protista.
