STATION 1
ECOLOGY REVIEW
1. Which organism below would be placed at the bottom of a food pyramid?
Organisms
Coyote
Eagle
Rabbits
Chipmunk
a. Coyote
Food Source(s)
Rabbits, squirrels
Rabbits, Squirrels, Chipmunks,
Grass, Berries
Nuts, Seeds
b. Squirrel
c. Chipmunk
d. Grass
2. Dead zones are low-oxygen areas that develop on the seafloor. Phytoplankton blooms are often
associated as the cause of these dead zones. An excessive nutrient from pollution fosters phytoplankton
blooms in the sea. Which of the following explanations would cause an increase in the occurrence of
dead zones?
a. Replacing coal-fired plants with solar panels
b. Farming practices that reduce runoff of pollutants
c. Rainfall patterns that increase runoff from terrestrial ecosystems
3. Hydrothermal vents form deep in the oceans when iron-rich magma is released from openings along
the seafloor. Bacteria thrive in the hostile, extremely hot, environment. If hydrothermal vents were to
become inactive and cold, which organism would succeed the original bacterial community?
a. Photosynthesizing organisms
b. Ocean mammals that tolerate cold waters and act as top predators
c. Bacteria that tolerate cold environments and feed on sulfur and iron
STATION 2
PLANT HORMONES
1. (IAN Page 32 RIGHT SIDE)
The plant hormone auxin:
Triggers
__Phototropism______________
Elongates cells for stem growth on the
darker__________ side of the plant
Produced by the _Apical
Meristem__________________________
__
2. The following plant interactions results in the growth of roots:
a. Ethylene is produced at a high rate resulting in rapid divisions of cells in darkness
b. Auxins released from apical meristem collect on the darker side of leaves
3. Roots typically grow downward while shoots grow upward. This phenomena may partially be the
result in differences regarding:
a. the concentration of auxins in response to gravity
b. percentage of open stomata in response to humidity
c. auxins do not play a role in gravitropism, only phototropism
STATION 3
VASCULAR TISSUES
1. How does a plant’s vascular tissue function to provide for the plant’s needs?
a. Xylem distributes sugars from the leaves to all other parts of the plant
b. Phloem carries water and nutrients from the root hairs up to the rest of the plant
c. Phloem carries the sugars to all parts of the plant for proper growth and energy
2. Most mosses will only grow to a couple of inches in height, while vascular plant will grow several feet
in height. What are mosses lacking to enable them to increase their average height?
a. lack roots
b. lack chlorophyll
c. lack vascular tissues
3. Students in Ms. Farmer’s class conduct an experiment involving celery stalks and food dye. After the
students have carried out their experiment, they examine the cross section of the celery stalk (shown
below) and find that the food dye has reached the upper stalk of the plant.
How do plant systems interact to make this movement of the food dye possible?
a. The roots lose water vapor in the soil, and the stems lose water vapor through the stomata
b. The roots absorb their own water and minerals, and the stem absorbs water via osmosis
c. The roots absorb water and minerals and move them up to the stem, while the stem moves food
produced in the leaves down to the roots
STATION 4
CELLULAR RESPIRATION, PHOTOSYNTHESIS, CELLULAR REPRODUCTION
1. An animal can wound a tree by scratching away the bark. The tree in return, may respond to wounds in multiple
ways. The diagram below illustrates a cross section of a tree with a healed wound.
What process works with the transport system to heal the wound?
a. Photosynthesis
b. Cellular Respiration
c. Cellular Reproduction
2.
Which of the following statements correctly compares photosynthesis and cellular respiration?
a. Cellular respiration produces water, but photosynthesis does not
b. Cellular respiration requires energy, but photosynthesis does not
What is the accurate formula of Photosynthesis? __6CO2 + 6H20 + ENERGY = C6H12O6 + 6O2
Which type of energy transformation occurs in photosynthesis? __LIGHT_________ to __CHEMICAL____________
STATION 5
PLANT ADAPTATIONS
1. A plant located in the rain forest will seek to trap sunlight so that light energy may be converted into chemical
energy. Which adaptation would be help this plant to accomplish this?
a. Small leaves
b. Large leaves
c. Large roots
2. Which of the following characteristics do both plant cells and photosynthetic bacteria share?
a. Cell walls made of lignin
b. DNA enclosed in the nucleus
c. Chlorophyll
3. This seed is best dispersed by:
a. animals
b. insects
c. wind
4. Climbing vines such as ivy coil around objects because the cells on the plant come into contact with an object
and…
a. the cells are stimulated by hormones to absorb more sunlight, thereby producing more energy
b. the cells release chemicals (hormones) that cause cells to grow faster on the other side of the plant
STATION 6
MISCELLANEOUS
1. There is a direct correlation between the amount of sunlight and the amount of carbon dioxide plant
leaves take in. In other words, as plant leaves are exposed to more sunlight, they will take in more
carbon dioxide. If light intensity is abnormally low however, leaves will give off carbon dioxide. Study the
graph below, and answer the question.
At the point on the graph where both the X and Y axis reads “0”, which process would be equal to the
rate of photosynthesis?
a. Transpiration
b. Cellular Reproduction
c. Cellular Respiration
2.
The largest amount of carbohydrates is manufactured by this structure: __PALISADE LAYER_
The structure that regulates gas exchange during photosynthesis/respiration : __STOMATA/GUARD
