The document details the objectives and significance of classifying organisms using a hierarchical taxonomic system developed by Carl Linnaeus in the mid-1700s. It outlines the levels of classification from kingdom to species and emphasizes the importance of taxonomy in identifying and protecting species diversity. The document also includes a mnemonic device for remembering the classification hierarchy and an assignment to classify specific organisms.

2. OBJECTIVES:
1.classify organisms using the hierarchical
taxonomic system
2.create mnemonic device on biological
taxonomic system
3.discuss the quotation “Where there is
unity there is victory”-Publilius Syrus

5. Classification: putting things
into orderly groups based
on similar characteristics.

7. WHY DO WE CLASSIFY
THINGS?

9. CLASSIFICATION
Taxonomy is the
branch of science
that names and
groups organisms
according to their
characteristics and
evolutionary history.

10. EARLY SYSTEM OF
CLASSIFICATION
•Aristotle grouped everything
into simple groups such as
animals or plants. Organisms
were first classified more
than 2,000 years.

EARLY SYSTEM OF
CLASSIFICATION
Plants were
placed into
three
categories
based on the
differences
in their
stems

12. THE SYSTEM OF
CLASSIFICATION
The modern classification system
was developed by the Swedish
scientist Carolus Linnaeus in the
mid 1700’s.
Some characteristics he used to
classify organisms were outside
appearance, internal organs, and
how body systems worked.

13. THE SYSTEM OF
CLASSIFICATION
 He developed a Hierarchy
(a ranking system) for
classifying organisms that
is the Basis for Modern
Taxonomy.
 For this reason, he is
considered to be “father”
of modern taxonomy.

14.  Kingdom - is the highest and most
comprehensive level of classification.
 Phylum – is a group of related classes.
 Class – is a group of related orders.
 Order – is a group of related families.

15.  Family – is a group of related genera.
 Genus – is a group of related species.
 Species – is a group of similar individuals
capable of interbreeding to produce fertile
offspring.

among organisms
Help us remember
organisms
communicate clearly
the identity of organisms
provide
stable names

21. CONCLUSION
The classification system for organisms have been
around for a long time. It has endured several
changes and is quite complex. Without it modern
biology could not exist, much in the same way that
a grocery store would go out of business if it did
not have a classification system. Thus,
classification of organisms help us to easily identify,
quantify and protect species diversity.
