TAXONOMIC CLASSIFICATION

TAXONOMIC
CLASSIFICATION OF LIFE
General Biology 2: Lesson No. 8 -Q3

After going through lesson, you are
expected to:
1. classify organisms into hierarchy of groups based on
similarities and distinct characteristics; and
2. describe the Linnaean system of classification;
3. name the living organisms.
General Biology 2: Lesson No. 8 Taxonomic Classification of Life
Most Essential Learning Competency
• Identify the unique/distinctive characteristics of a specific taxon to other taxa
(STEM_BIO11/12IIIhj-15).

INTRODUCTION
Every individuals have their own and unique characteristics.
Each is varied and different from one another.
Similarities and differences of individuals rooted for science of
classification-Taxonomy
At present, classification of living organisms made a significant
contribution for different applications.

WHAT’S NEW
Activity 1. SAY MY NAME
Direction: Share to the class about the
meaning of your name.
Guided Questions:
1. Do you know how your parents
came up with your name?
2. What’s the meaning behind your
name?

WHAT I
PRE-TEST WITH A TWIST
Direction:
• The class will play a naming game.
• A category will be given about anything and each
student should give a name related to the given
category.
• Those who failed to name or give a wrong name will
answer a question for the pre-test.

5. What is the purpose of binomial nomenclature
system?

D. Avoid confusion that can occur when using common names

Direction: Give the correct
sequence of taxonomic hierarchy.
Arrange each term from highest to
lowest order.

Activity 3. Create your Own
Mnemonics
Direction:
Make your own
mnemonic device of
taxonomic hierarchy.
Do this activity on a
clean short bond
paper. Your output
will be assessed
using this rubrics

Questions:
1. Based from the videos presented, what is the highest
rank in classifying organism?, What is the lowest?
2. How many Domains and Kingdoms in the classification
are there?
3. Can you give one kingdom in the list and give a short
description?

EARLY TAXONOMIST
•2000 years ago, Aristotle
was the first taxonomist
•Aristotle divided
organisms into plants &
animals;
•He subdivided them by
their habitat ---land, sea,
or air dwellers

EARLY TAXONOMIST
•John Ray, a botanist, was
the first to use Latin for
naming
• His names were very
long descriptions telling
everything about the
plant

EARLY TAXONOMIST
• Carolus Linnaeus is 18th century
taxonomist
• Classified organisms by their structure
Developed naming system still used
today
• Called as the “Father of Taxonomy”
• Developed the modern system of
naming known as binomial
nomenclature = Two-word name
(Genus & species)

BENEFITS OF CLASSIFYING

RULES OF BINOMIAL NOMENCLATURE
• There are two international codes which are agreed upon by all the
biologists over the entire world in giving name of the living organism.
It follows protocols in naming to make sure that each organism gets a
specific name and that name is globally identified. They are:
International Code of Botanical Nomenclature (ICBN) – Deals with
the biological nomenclature for plants.
 International Code of Zoological Nomenclature (ICZN) – Deals with
the biological nomenclature of animals.

• Additionally, in binomial nomenclature rules for writing the scientific
names of organisms include the following:
 All the scientific names of organisms are usually Latin. Hence,
they are written in italics.
There are two parts of a name. The first word identifies the genus
and the second word identifies the species.
When the names are handwritten, they are underlined or
italicized if typed. This is done to specify its Latin origin

Homo sapiens

= Generic Name
Specific epithet
=species name

Directions: Write the scientific name of the following organisms, based your answer in the
data found in the table below.
Rabbit : Oryctogalus cuniculus
