Transcript Plant nomenclature and taxonomy

Plant nomenclature and taxonomy
Taxonomy is the science of naming of
leaving organisms and their correct
integration into the existing system of
nomenclature.
The exact naming (taxonomy) and an
understanding of the species
relationship to other species is an
essential basis for pharmacognostic
work.
Only taxonomy allows the correct
identification of a botanical drug, and
consequently is the basis for further
pharmacological, phytochemical,
analytical, and clinical study.

Plant nomenclature and taxonomy
Morphological and microscopical
character of the plant
organs plays an important
role in identifying a
botanical drug.
Based on the analysis of
character, plants are
classified into the following
levels or categories:
Kingdom
Phylum: (plural=phyla)
By Dr. Youssef Ibrahim Ph.D.
Class
Order
Family
Genus: (plural=genera)
Species
Each formal grouping at any
given level is a taxon
(pl.,taxa)
Plant nomenclature and taxonomy
Closely related species grouped
together in a common genus
Related genera can be grouped in a
more inclusive group called
family
Families are grouped into order
Orders are grouped into classes
classes are grouped into phyla
Biologists group phyla can be
assigned into six Kingdoms
By Dr. Youssef Ibrahim Ph.D.
1-Archaebacteria (unicellular
prokaryotic cells without
nuclei)
2-Eubacteria (bacteria)
3-Protista (protozoa)
4-Fungi (Yeast)
5-Planta (Complex multicellular
organisms, carry out
photosynthesis)
6-Animalia (multicellular organisms
that eat other organisms for
nutrition)
