There have been several attempts to classify living organisms since the birth of humanity. They are: (i) Monera (ii) Protista (iii) Fungi (iv) Plantae (v) Animalia • The main criteria for classiÆcation of organisms into Æve kingdoms include cell structure, thallus organisation, mode of nutrition, reproduction and phylogenetic relationships. Kingdom Monera • Has bacteria as sole members.
Biological Classification: Understanding the Diversity of Life. In the vast tapestry of life that envelops our planet, organisms of all shapes, sizes, and functions coexist. From the towering trees of the rainforests to the microscopic bacteria hidden in the soil, every living entity has a place and role in the intricate web of life.
