RUBBER DUCK REVIEW!
REVIEW QUESTIONS
A: A
While observing an
Elodea plant cell through
a microscope, a student
noticed some small,
moving green disks.
These organelles were
most likely which of the
following?
a. chloroplasts
b. leucoplasts
c. mitochondria
d. ribosomes
A: Lack of water
Why did this plant
respond this way?
A: SUGAR
What does
PHOLEM
transport?
A: WATER
What does
XYLEM
transport?
A: C
Oleander Leaf Scorch is a disease that affects oleander plants in
Southern California. The plant is infected in an interesting way.
There is an insect that drinks the fluid from the oleander xylem.
The insect is carrying a bacterium, Xylella fastidiosa. When the
insect begins to drink, it injects the bacterium into the xylem. The
xylem is then blocked by all of the bacteria.
What negative effect would this have on the oleander plant?
a.
b.
c.
d.
The oleander would not be able to cross-pollinate.
The bacteria would provide nutrients for the plant, so the oleander
would stop photosynthesizing.
The oleander would die due to loss of water.
The insect would drink nectar from the flowers instead
A: Stomata
What was the
structure called
that Ralphie fell
through in the
Magic School
Bus “Gets
Planted?”
A: Guard Cells
What are the 2 cells called that make up the
Stomata called?
A: C
The stomata will open
or close in response
to water pressure in
the:
a. root cells
b. cell walls
c. guard cells
d. xylem
A: hot & dry
What is the climate like in this
biome?
A: Desert
What biome is this?
A: A
Cacti keep their stomata
closed for much of the
day. What is the result of
the cacti keeping their
stomata closed?
a. It limits water loss
through transpiration.
b. It conserves oxygen
produced in
photosynthesis.
c. It recycles carbon dioxide
within plant systems.
d. It protects plant tissues
from predators.
A: Pollination = Animals are drawn to the flowers bright
colors. While there they suck the sweet nectar out of flowers and get coated w/
pollen and brush against the pistil. The pollen tube grows from the stigma 
style  ovary and fertilizes the seeds!
What is the process above
called? Describe this process.
A: Death
What does the suffix “-cide” mean?
A: A
A research scientist is attempting to
create a chemical herbicide that
acts by causing the pollen to be
deformed. What is expected to
happen in plants sprayed with this
chemical?
a. non-functioning flowers
b. root rot
c. withered stems
d. yellow leaves
A: The Mutt
Which dog would have a better chance of
survival in the wild, the pure breed that is
homozygous for its traits or the mutt that is
heterozygous for his traits?
A: His genes are more diverse
Why does the heterozygous
mutt have a better chance at
survival in the wild?
A: A
Which ecosystem has a better chance of
surviving when environmental conditions
change over a long period of time?
a.
b.
c.
d.
One with a great deal of genetic diversity
One with plants and animals but no bacteria
One with animals and bacteria but no plants
One with little or no genetic diversity
A: Water, Carbon Dioxide & Light
What do plants NEED in order to survive?
A: LIGHT
PHOTOTROPISM is when a plant
grows toward a stimulus. What
stimuli do you think it is growing
toward?
A: C
A.
B.
C.
D.
Some species of kelp anchor
themselves to the seafloor.
These species have small air
sacs, called air bladders, at the
base of each leaf. The air
bladders raise the top of the kelp
to the water's surface. What
advantage do air bladders give
the kelp?
They allow the kelp to obtain
more salt from the water.
They prevent the kelp from
breaking during a storm.
They allow kelp leaves to receive
greater amounts of sunlight.
They provide the kelp with
protection from herbivores.
A: TUNDRA
What BIOME is this?
A: plants are
small & they
grow close to
the ground
How are plant life
adapted to this
environment?
A: A
a.
b.
c.
d.
Which of the following is
most likely to disrupt an
arctic ecosystem?
global warming leading
to melting of glaciers
drought due to El Nino
weather pattern
oil spills from ruptured
wells in the Gulf of
Mexico
a massive tornado
A: The bull is an
herbivore, &
the bear is an
omnivore.
What differs in these
2 consumers diets?
A: The prey can reach its
carrying capacity.
What happens to the population that is
preyed on by predators when the
predators are removed?
A: C
a.
b.
c.
d.
If an entire black bear population
disappears, what is likely to happen
to the fish population on which it
preys?
The fish population would decrease.
The fish population would be
unaffected
The fish population would increase.
The black bear population doesn’t
affect the fish population.

AN ENVIRONMENT advocate warns that rainfall is expected to increase by at least 14 percent
in East Asia as the world gets hotter due to climate change.Elisea G. Guzon, Presidential
Assistant on Climate Change, said climate change contributes to the risk of more rainfall
because the world is experiencing “global fever” due to green gases.Guzon, however, said the
increase in rainfall is not evenly distributed among East Asian countries.“The major
consequence of climate change is the variability of precipitation which means that too much heat
can cause too much evaporation that leads to rainfall,” she said during an environmental forum
at Xavier University over the weekend.Guzon said greenhouse gases like carbon dioxide and
methane can cause greenhouse effect.“It will continue to get hotter in this century and beyond,”
she warned as she pointed to people who are “causing a dangerous trend.” She, however, failed
to elaborate.. Guzon said an average of 20 typhoons enter the Philippines every year and
because of climate change, the typhoons will become either stronger or will bring in more rain.In
December, Tropical Storm Sendong devastated some parts of Cagayan de Oro and Iligan City,
which left thousands dead and missing.The weather bureau said ‘Sendong’ poured in more rain
compared to ordinary typhoons, much even more than Typhoon Ondoy.According to Graciano
Yumul, officer-in-charge of the Philippine Atmospheric Geophysical and Astronomical Services
Administration (Pagasa), the normal rainfall in Cagayan de Oro for the month of December is
113.2 millimeters (113.2mm).Guzon added that the rise in sea level is also the effect of climate
change.“The glaciers are melting because of heat. The rising sea level will erode beaches,
intensify flooding, inundate wetland and other low-lying lands and increase the salinity of rivers,
bays and ground water tables.” “We have to plan and work together, government and private
sectors, non-government organizations, the academe. Everyone should help each other
because it is our shared responsibility,” she said.
A: A
Based on the journal entry above, how
did this environmental change affect
the environment?
a. It caused increased rainfall in East
Asia
b. There will be more grass in a certain
meadow.
c. A small creek dries up every summer.
d. Additional ice will be added to the
glaciers.
