Classifying Organisms
HANDS-ON LAB
It is estimated that there are approximately 8.7 million species
of organisms on the planet, with thousands more discovered
each day. A species is a group of similar organisms that can
mate with each other and produce offspring that can also mate
and reproduce. Biologists place similar organisms into groups
based on characteristics they have in common. Classification
is the process of grouping things based on their similarities. To
classify the organism in Figure 1, you'd first need to know about
its characteristics. Then you could figure out which group it
belonged to.
Organize items based on
similar characteristics.
Write About It Pick
a favorite animal or plant.
What is it that you find most
interesting? In your science
notebook, describe its
characteristics.
Linnaean Naming System In the 1730s, biologist
Carolus Linnaeus arranged organisms in groups based
on their observable features. Then he gave each organism
a two-part scientific name. The first word in the name is
the organism's genus, a group of similar, closely-related
organisms. The second word is the species and might describe
where the organism lives or its appearance. This system in
which each organism is given a unique, two-part scientific
name that indicates its genus and species is known as
binomial nomenclature. Today, scientists still use this naming
system that classifies organisms according to their shared
characteristics.

harder to classify than others!
