Allows scientists to
accurately
identify
individual
species
Scientific names always have
two
words
More
accurate methods to classify organisms
Studying
amino acids
in
proteins
Studying sequences of
bases
in
DNA
Morphology
Outward
appearance
of an organism
Anatomy
Internal
structure
of an organism
Dichotomous key
A way of
identifying
an organism, by working through
pairs
of
statements
that lead you to its
name

Characteristic
features of animals
Cells have a
nucleus
, but no
cell walls
or chloroplasts
They feed on
organic
substances made by other living
organisms
Characteristic
features of plants
Cells have a
nucleus
and cell walls made of
cellulose
, often contain chloroplasts
They feed by
photosynthesis
They may have
roots
,
stems
and
leaves

Fungi
Colourful
and
easy
to spot
Made up of
microscopic
threads called "
hyphae
"
Cell
wall
not made of
cellulose
Decomposers
Uses
of fungi
Eat them as
mushrooms
Use single-celled fungus (yeast) to make
alcohol
and
bread
Obtain antibiotics such as
penicillin
Characteristic
of fungi
Usually
multicellular
but some unicellular
Chitin
cell wall
Have nuclei and cell walls, not made of
cellulose
Don't have
chlorophyll
Feed by
digesting
waste
Contain
ribosomes
Characteristic
of
prokaryotes
Usually
unicellular
No
nucleus
, no
mitochondria
Cell walls
not made of
cellulose
Circular loop
of
DNA free
in cytoplasm
Often have
plasmids
Characteristic
of amphibians
Smooth
and
moist
skin with
no
scales
Eggs
no shell and laid in
water
Tadpoles live in
water
, adults live on
land
Tadpoles have
gills
for
gas exchange
, adults have
lungs
Characteristic
of reptiles
Dry scaly
skin
Lay eggs with
soft
shell
Characteristic
of mammals
Hair
or
fur
on skin
Young develop in
uterus
, attached to
mother
by
placenta
Females have
mammary
glands
that produce
milk
Have

, pinnae (ear flap),
sweat
glands
,
diaphragm
