Classification
Name:
1. The figure below shows the eight levels of the classification system. Using the information contained in the
passage, insert the correct label in the space provided on the left side of the figure. On the right side of the
figure, compose a sentence that describes the level. The first one has been done for you.
Linnaeus worked out a broad system of classification for plants and animals in which an organism’s form and
structure are the basis for arranging specimens in a collection. He later organized the genera and species that
he described into a ranked system of groups that increase in inclusiveness. The different groups into which
organisms are classified have expanded since Linnaeus’s time and now consist of eight levels.
Similar genera are grouped
into a family. Similar
families are combined into
an order. Orders with
common properties are
united in a class. Classes
with similar characteristics
are assigned to a phylum.
Similar phyla are collected
into a kingdom. Similar
kingdoms are grouped into
domains. All living things
are grouped into one of
three domains. Two
domains, Archaea and
Bacteria, are each
composed of a single
kingdom of prokaryotes.
The third domain, Eukarya,
contains all four kingdoms
of eukaryotes.
Read the passage below. Then answer the questions that follow.
Biologists have organized living things into six large groups called kingdoms. Biologists group organisms in the
different kingdoms based on the organisms’ similarities. Most biologists use the six kingdom system. The
characteristics of these six kingdoms are summarized in the table below. Some are left blank for you to fill in.
