Introduction to Living
Things
Taxonomy
 The scientific study of how living things are
classified.
Response
What is it? Give an example.
When a plant grows toward light,
the plant’s action is a response.
Classification Level
 What is the broadest classification
level?
DOMAIN
Which characteristic could be used
to place organisms into kingdoms?
A. Their ability to make food
or
B. Where they live
What does an organisms scientific
name consist of?
 A. Kingdom name & Phylum name
Or
 B. Genus name & Species name
Which group contains only
multicellular heterotrophs?
 A. animals
or
 B. plants
Scientists get information about
evolutionary history of species by:
A. comparing body structures
or
B. observing what they eat
What is an organism that
makes its own food called?
A. heterotroph
or
B. autotroph
Which is more abundant in
living cells?
 A. water
or
 B. proteins
What happens when two
organisms share many
classification levels?
 A. they have more characteristics in
common
 B. it’s easier to tell them apart
Redi and Pasteur helped
demonstrate that:
Living things do not arise from
nonliving materials.
Spontaneous generation is a
mistaken idea because:
Living things are produced by other
living things.
Which kingdoms include
unicellular and multicellular
organisms?
Fungi & Protists
Charles Darwin’s theory of
evolution had a major impact on
classification.
Gradual change in species
over time is evolution.
Which domains include only
prokaryotes?
Bacteria & Archaea
Each genus of organisms contain
one or more species.
Archaea aren’t classified with
bacteria because its chemical
makeup is different.
If an owl & robin share the same
kingdom, phylum, and class, they
share more characteristics than
an owl and bat that share the
same kingdom and phylum.
Biologists find taxonomy useful
because it gives them
information about an organism
based on classification.
Stable internal conditions held
by an organism is homeostasis.
Genus is the first word in an
organism’s scientific name.
Evolutionary history suggests
bats and whales have similar
characteristics.
A taxonomic key consists of
paired statements about
characteristics of organisms.
