classification system?
a. Artificial system
b. Natural system

d. A & B
2. Why do animals need to be
named in scientific and in Latin?
a. To make science sound
hard
b. To avoid ambiguity and
confusion that can be
created with native names

language ever since

originated in Latin

kingdom eubacteria?

8. Name the tool that is a form of an
identification key that consists of
a series of choices that lead the
user to the correct identification
of an organism.
a. Artificial system
b. Dichotomous key
c. Natural system
d. Biological system
9. What are the major
characteristics used in
classification?
a. Morphological features
b. Biochemical and
physiological features
c. Genomic features
d. All of the above
10. What is the concept that
determines and classifies species
as a group of organisms that are
able to interbreed and produce
fertile offspring in a natural
environment?
a. Biological species
concept
b. Morphological/topologica
l species concept
c. Ecological species
concept
d. Phylogenetic species
concept
11. What is phylogenetic species
concept?
a. Concept that determines
and classifies species
based on comparisons of
physical characteristics or
traits with the type
sample or specimen
b. Concept that determines
and classifies species
based on its role in nature
and it’s adaptation to
specific functions in a
community.
c. Concept that determines
and classifies species
based on phylogenyevolution history of
organism.
d. Concept that determines
and classifies species as a
group of organisms that
are able to interbreed and
produce fertile offspring
in a natural environment.

is a form of an identification key that
consists of a series of choices that
lead the user to the correct
identification of an organism
is a branch of systems biology that
involves identification, describing,
naming and classification of
organisms based on the natural
relations of all other organisms
lack organs and are extremely diverse
from each but do not fit also into
other kingdoms
involving comparisons of chemistry
of biological molecules such as amino
acids and nucleotides and how
organisms function chemically at
different levels on their bodies.
is a formal system of naming species
in which each organism’s name has
two parts. The first part of the name is
a genus (generic, plural) name to
which a species belongs and the
second part is the specific epithet or

involving comparisons of appearances
of organisms
involving comparisons from DNA,
RNA and protein analysis,
comparisons of chromosome number
and structure and comparisons of
genomic sequences between
organisms
c. Fill in the Blanks
1. The first widely accepted system was developed by a Greek philosopher Aristotle
who classified organisms as either plant or animals.
2. The natural system of classification is the most useful system to biologists because it
takes into account certain relationships among all organisms, important features
shared by as large group as possible, and puts related organisms into distinct groups.
3. Different taxa which occur at different levels in the hierarchy in order of descent
include Domain, Supergroup, Kingdom, Phylum or division, class, Order, Family,
Genus and Species.
4. Organisms are classified into domains based on the types of cells, into super groups
based on sequencing of genetic material and into kingdoms based on the types and
structure of their cells and on the modes of their nutrition.
5. When the main features or characteristics of a group of organisms are known and
described, a systematic key plan can then be designed to be used for identifying and
categorizing a new unknown or unfamiliar organisms.
