TAXONOMY
Taxonomy is the study of classification and nomenclature. The study of taxonomy began with
God. The father of modern taxonomy is Carl Linnaeus because he published a book called
the binomial system of nomenclature. In that book every organism has a two part name.
One part is the generic epithet and the other part specific
TAXONOMIC HIERARCHY
Recall that living things are grouped into five Kingdoms
1. Kingdom Monera: consisting of blue green bacteria
2. Kingdom Protista: Consists of organisms with dual( animal and plant) features
3. Kingdom Mycota: Consist of fungi e.g mushroom, yeast, ringworm, rhizopus.
4. Kingdom Plantae: Consists of Green plants.
5. Kingdom Animalia: Consists of animals.
There are some demerits in the five Kingdom classification
1. There's no place for virus
2. Some kingdoms contain plant-like and animal-like organisms
There are seven major taxonomic hierarchies. There are;
● Kingdom
● Division in plant studies(Phyla in animal studies) NOTE: all division must end in phyta
● Class (Standard ending - physia)
● Order( Standard ending - ails)
● Family( Standard ending - aceae)
● Genus (No standard name ending)
● Species ( They are often feminized to rhyme)
All botanical names are regarded as feminine.
A plant can be named based on
● Origin (Senegalese - Senegal
● Name of popular scientist
● Distinguishing feature (erythro - red,)
● Poetic origin (Theobroma cacao - Theobroma is a Greek goddess)
There are 7 major taxonomic ranks just as there are 7 minor taxonomic ranks. The insertion or
addition of a prefix to any of the major rank make the resulting word a minor. The prefixes are;
● Sub
● Supra
● Infra
CLASSIFICATION
It Is the grouping of organisms. There are four types of classification systems.
1. ARTIFICIAL: When plants are classified based on the ecosystem services the offer.
Such a system is called artificial. Artificial system of classification classifies organisms
based on their uses. ( Problem- one plant can be classified for different uses)
