Answer:
Taxon
is a scientific term used for different categories of classification.
Taxonomic hierarchy is position of different taxonomic categories is
ascending order,which describes the complete systematic position of any living
organism.
Given below is the flow diagram of taxonomic hierarchy
As we move up in the taxonomic hierarchy
the number of shared characters become less.
Taxon
Plant
Animal
Kingdom
This
is the highest category of classification, which includes all organism that
share a set of distinguishing common characters.
Kingdom-Plantage
e.g.,
kingdom-Animalia.
Phylum/Division
A
It includes different classes having a few common characters.
Division
is used in plants.
Phylum
is used in animals e.g. Chordata includes classes like Pisces, Amphibia,
Pisces, Amphibia, Reptilia, Aves and Mammalia,
Class
Represents
organisms of related orders.
Found
only in flowering plants, i.e., monocotyledoneae and dicotyledoneae.
Comprised
of related orders i.e., class- Mammalia
Order
It
is an assemblage of families resembling one another in few characters. These
characters are less similar as compared to characters of many genera placed
in a family.
e.g.,
dicotyledoneae consists of order Rosales polemoniales, sapindales, ranales
etc. on the basis of floral characters.
e.g.,
class-Mammalia includes order chiroptera, marsupialia, rodentia, cetacean,
carnivore.
Family
It
includes one or more genera differentiated from others related families by
certain characteristic differences (both vegetative and reproductive).
e.g.,
Order Polemoniales comprises families like Solanaceae and Convolvulaceae
e.g.,
order carnivore include families like Felidae (cats), canidae (dogs, foxes),
ursidae (bears) etc.
Taxon
Plant
Animal
Genus
It
is the first higher category above the species level. It is a group of
species, which are related and have fever characters in common as compared to
species.
e.g.,
Family-Solanaceae comprises of genus Solanum.
e.g.,
hlidae comprises of genus Panthera (lion, tiger) and Felis (cats)
Species
It
is group of individuals with similar morphological characters, which are able
to interbreed and produce individuals of their own kind.
e.g.,
Solanum nigrum (brinjal) and Solanum tuberosum. Here nigrum and tuberosum are
two species of Solanum genus.
e.g.,
The genus Panthera includes species Leo (lion) and Panthera Tigris (tiger).
