Classification of Living Organisms

The video tutorial explains the classification of living organisms into six kingdoms: Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia. It covers key characteristics such as cellularity (unicellular or multicellular), cell type (eukaryotic or prokaryotic), nutritional methods (autotrophic or heterotrophic), and the presence of cell walls. The video also provides examples of organisms in each kingdom, highlighting their unique features and environments.
