"A" represents carbon dioxide produced by the plant and "B" represents oxygen produced by the duck
"A" represents oxygen produced by the plant and "B" represents carbon dioxide produced by the Duck
"A" represents the sunlight received by the plant and "B" represents the oxygen produced by the duck
Which correctly explains the diagram?
Light Energy to Chemical Energy to Thermal Energy
Light Energy to Thermal Energy to Mechanical Energy
Thermal Energy to Light Energy to Chemical Energy
Thermal Energy to Light Energy to Mechanical Energy
What is produced in the leaves of the plant?
oxygen and water
carbon dioxide only
glucose and oxygen
oxygen only
Which describes the transfer in this image?
Carbon Dioxide from the air becomes glucose in the plant. The deer ingest the glucose and it becomes carbon.
Carbon Dioxide from the air becomes water in the plant. The deer ingest the water and it becomes oxygen.
Oxygen from the air becomes carbon dioxide in the plant. The deer ingest the carbon dioxide and it becomes carbon.
Water from the air becomes Oxygen in the plant. The deer ingest the Water and it becomes Oxygen.
Cellular respiration is the process that our cells use to ….
convert sugar (glucose) into energy (ATP)
break food down into smaller molecules (sugars)
makes acid
breathe
Where do animals get the glucose that is needed for cellular respiration?
from the exercise they get
from the water they drink
from the food they eat
from the sunlight they get
When there is not enough light.....
...the rate of photosynthesis is at the optimum.
...the rate of photosynthesis is limited.
...the rate of photosynthesis will not be affected.
Why does the amount of water affect rate of photosynthesis?
It is produced by the reaction
It is used in the reaction
It affects the enzymes responsible for the reaction
The plant cells have to stay turgid
The following graph represents a plant in a sealed ecosystem where the levels of carbon dioxide (pink) and oxygen (green) can be observed.
Which of the following explains the changes to the gas levels over the 24 hour period?
Carbon increases at night because there is less photosynthesis and more cellular respiration occuring in the plant
Carbon increases during the day because there is less photosynthesis and more cellular respiration occuring in the plant
Oxygen increases at night because there is more photosynthesis occuring in the dark
cellular respiration does not occur in plants, so carbon dioxide decreases during the day in the light and never increases again.
Photosynthesis and cellular respiration both involve taking in and giving off gases. During photosynthesis, what gas is released? (product)
Carbon Dioxide
Glucose
Oxygen
Water
Photosynthesis and cellular respiration both involve taking in and giving off gases. During cellular respiration, what gas is released? (product)

Glucose
Oxygen
Water
Photosynthesis and cellular respiration both involve taking in and giving off gases. During cellular respiration, what gas is taken in? (reactant)
Carbon Dioxide
Glucose
Oxygen
Water
The products of photosynthesis are the reactants in cellular respiration. What is the purpose of cellular respiration?
To create energy.
To create sunlight.
To create glucose.
To remove energy.
In photosynthesis, which molecule is synthesized as a source of energy for cellular respiration?
Protein
Sunlight
Oxygen

When do enzymes function best?
Under specific temperature and pH levels.
Under perfect atmospheric conditions.
When co-enzymes are present.
In any condition.
Enzymes are an example of
Lipids
Carbohydrate
Protein
Nucleic Acid
Chloroplast
Organelle that does photosynthesis
Organelle that does Cellular Respiration
Organelle that builds protein

Heterotroph
Plant
The products of photosynthesis are:
CO2 and H2O
the reactants of cellular respiration
sunlight and ATP
plants and other producers
C6H12O6
The reactant of photosynthesis
Glucose: the product of photosynthesis
The product of cellular respiration
Glucose: the energy made by cellular respiration
The difference between aerobic and anaerobic respiration:
Aerobic respiration only occurs in plants and anaerobic respiration occurs in heterotrophs.
Aerobic respiration uses oxygen and anaerobic respiration does not use oxygen.
Aerobic respiration does not create as much ATP as anaerobic respiration.
Aerobic respiration only complete glycolysis, while anaerobic respiration complete the electron transport chain.
The equation for photosynthesis is:
C6H12O6 + 6O2 > ATP + 6CO2 + 6H2O
6CO2 + 6O2 > sunlight + C6H12O6 + 6H2O
6H2O + 6CO2 + sunlight > C6H12O6 + 6O2
C6H12O6 + 6CO2 + sunlight > 6H2O + 6O2
A word synonymous with a producer:
Consumer
Carnivore
Heterotroph
Autotroph
Ribosome
→ Carbon dioxide + Water
→ Oxygen + Water
→ Glucose + Water
