Six Kingdom Classification

Well some time ago all living things were classified in five kingdoms but now scientists classify all living things into six kingdoms.

Based on Ribonucleic Acid (RNA) studies, "Carl Woese" divided the prokaryotes (classified till now as the Kingdom Monera) into 2 groups, called Archaebacteria & Eubacteria. This means that there is no more consolidated Monera Kingdom.

The Six Kingdoms are as follows :

(1). Archaebacteria Kingdom Classification : Archaebacteria are probably the oldest living organisms on the planet earth. Archaebacteria are prokaryotes and uni-cellular. Archaebacteria can be found in very harsh (i.e. rough & tough) conditions, such as at the in volcanic vents and/or bottom of the sea. Early Earth's atmosphere was filled with poisonous and harmful gases and the climate was very hot, there nothing could survive but the "Archaebacteria". When the Earth's conditions settled down and oxygen was introduced to the atmosphere then slowly the modern organisms emerged.
Archaebacteria Kingdom Examples : Methanogens, Halophiles, Thermophiles, Thermoacidophiles etc.

(2). Eubacteria Kingdom Classification : The eubacteria are more complex, and common, than the archaebacteria. It is the eubacteria that most of the people talk about when they say bacteria, because they live in more neutral conditions. Eubacteria can be found everywhere around us such as in our food, our body etc.
Eubacteria Kingdom Examples : Clostridium perfringens, Bacillus antracis, Bacillus pneumonia, Clostridium tentani, Cyanobacteria, Salmonella etc.

(3). Protista Kingdom Classification : This kingdom includes unicellular from usually found in aquatic habitats. On the basis of mode of nutrition they are autotrophic, parasitic, and saprophytic. Diatoms flagellates and protozoa come under this kingdom. Egulena have both heterotrophic and autotrophic mode of nutrition. So, it is placed between plant and animal.
Protista Kingdom Examples : Amoeba, Paramecium, Euglena, Plasmodium etc.

(4). Fungi Kingdom Classification : This kingdom includes non-green plants. It has saprophytic nutrition and growing on dead and decaying organic matter. The cell wall is composed of chitin.
Fungi Kingdom Example : Yeasts, Molds, Mushroom etc.

(5). Planatae Kingdom Classification : Planatae kingdom includes all plants except some fungi, diatoms, algae and member of monera and Protista.
Planatae Kingdom Examples : Oak, Cactus etc.

(6). Animalia Kingdom Classification : Mostly all remaining animal comes under this kingdom except protozoan.
Animalia Kingdom Examples :- Horse, Tiger, Kangaroo etc.
