2. Protista:-
These unicellular creatures are similar to the kingdom but these are eukaryotic.
3. Plantae:-
All colored multicellular plants which frequently exhibit the phenomenon of photosynthesis and whose cells have vacuole have been kept. The organisms like mass, algae almost all plants.
4. Fungi:-
The organisms are eukaryotic and the phenomenon of photosynthesis does not occur. Nutrition in such cells are completed by the absorption and so cells are heterotrophic these are saprophytes or parasites, cell walls are made up of chitin.

Nomenclature of the organism
Nomenclature means an international system of standardised New Latin names used in biology for kinds and groups of kinds of animals and plants.

First generic name and second species name.
Example:-
scientific name (man)- homo sapiens linn
Here homo: generic name
Sapiens: spices name
Linn: name of taxonomer scientist
