- Lehius is considered as the father of the classification of the living world.
- Five kingdoms were proposed by Robert Weather.
- Monera Kingdom
- These are the prokaryotic organisms. Organized nuclei and cell parts not found in these organisms.
- Depending on the level of nutrition, it can be both autotrophic or heterotrophic.
- Among these, reproduction occurs by conjugation.
- Mycoplasma, the smallest cell, also survives without oxygen.
- All bacteria come into this kingdom. Examples are indigo green algae or cyanobacteria, spherical coccus, bacilli, spirilla, vibrio, etc.
2. Protista Kingdom
- It includes unicellular, eukaryotic organisms. Organized nucleus and membrane-bound cells are found in their cells.
- In this class of organisms, a structure called cilia or flagella is found for movement.
- They are both autotrophic and heterotrophic.
- Reproduction occurs by gamete fusion and conjugation.
- Examples are unicellular algae Paramecium, Amoeba, Euglena, Diatom, Protozoa etc.
3. Fungi Kingdom
- These are heterogeneous and eukaryotic organisms.
- They absorb nutrition from decaying organic material hence they are also known as Saprophyte.
- Some fungi depend on live plants and animals for exploitation, called parasites. Advertisement
- The fungi are fibrous. It has a structure similar to a long thin thread called a fungus. Its net is called a fungus trap.
- Some fungal fibers are continuous tubules that have a multicellular, cytoplasm filled with cytoplasm. They are called cellular fungal fibers.
- The cell wall of the fungus is made up of chitin and polysaccharide.
- Fungi include fungal reproduction, asexual reproduction, asexual reproduction.
- Examples are mushrooms, mushrooms, yeast.

Some Other Animal
- Both DNA and RNA are not found together in any virus. A virus will have either DNA or RNA. Plant viruses have a threaded RNA.
- Animal viruses have one or double-stranded RNA or DNA.
2. Viroids: lack RNA and protein coating.
3. Lichen: It originates from the symbiotic saliva of algae and fungi. Lichen is used as an indicator of pollution.
