HW: Kingdoms Review Entry Card
Castle Learning Microscope Review – Due
Tuesday, January 5th.
Identify the 7 levels of
classification.
Describe
what occurs
to the
number of
organisms
in each level
as you
move down
the levels.
Describe
what occurs
to the
similarity
between
organisms
in each level
as you
move down
the levels.
Before Linnaeus developed his naming system, plants and
animals were named by a series of Latin words that
described the physical appearance of the organism. This
was very confusing. For example, let’s look at the first
name of the honey bee.
Apis pubescens, thorace
subgriseo, abdomine fusco,
pedibus posticis glabris utrinque
margine ciliatus.
This means “fuzzy bee, light
gray middle, brown body, smooth
hind legs that have a small bag
edged with tiny hairs.” Linnaeus
named it Apis mellifera which
means “honey-bearing bee.”
Is their a taxon that is
LARGER
than a
KINGDOM????
Domain Bacteria is
familiar to most
people when
associated with
human or animal
disease. However,
there are many
bacterial species do
not (and cannot)
cause disease. Many
species even play
beneficial roles by
producing antibiotics
and food. The soil
teems with free-living
bacteria that perform
many essential
functions in the
biosphere, e.g.
nitrogen fixation.
Domain Eukaryota
include protists and
the cells that make
up fungi, plants,
animals.
Domain Archaea wasn't
recognized as a major
domain of life until quite
recently. Scientists were
studying different
prokaryotes and found
that there were 2 different
groups: those that lived at
high temperatures or
produced methane
clustered together as a
group. Because of their
difference in genetic
makeup, scientists
proposed that life be
divided into 3 domains.
• Unicellular
Archea
• Prokaryotic
• Autotrophic or heterotrophic
• Found in extreme environments
– oxygen-free
– hot acidic waters of sulfur springs
– bodies of concentrated salt water
Hot Springs
Hydrothermal vents
The hot springs of
Yellowstone National
Park, USA, were
among the first places
Archaebacteria were
discovered.
• Unicellular
Eubacteria
• Prokaryotic
• Autotrophic or
heterotrophic
Yogurt contains lactobacteria,
intestine-friendly bacterial
cultures that foster a healthy
colon, and even lower the risk of
colon cancer. Lactobacteria,
especially acidophilus, promotes
the growth of healthy bacteria in
the colon. The more of these
intestine-friendly bacteria that
are present in your colon, the
lower the chance of colon
diseases. Basically, the friendly
bacteria in yogurt seems to
deactivate harmful substances
before they can become
carcinogenic.
• Found everywhere
– most are helpful (produce vitamins)
– some cause disease (Ex: Strep throat)
Streptococci pyogenes
Salmonella enteriditis
Strep throat
Salmonella
poisoning
Fun Fact: There are more bacteria in one
person's mouth than there are people in
the world.
Protists
• Unicellular
• Eukaryotic
• Animal-like  heterotrophic
– Protozoa
Ex: Amoeba, paramecium
• Plant-like  autotrophic
–Algae
Fungi
Fungi • Multicellular
• Unicellular  yeast
• Eukaryotic cells
• Heterotrophic
– Decomposers  absorb
nutrients of dead
organisms
• Mushrooms
•Mold
• Multicellular
Plants • Eukaryotic cells
• Autotrophic
• Ex: Trees, grasses…
•
Multicellular
Animals
• Eukaryotic cells
• Heterotrophic
• Examples: Humans,
jellyfish, insects, dogs,
fish…
