Which of the following is responsible for the exchange of gases between the plant and the atmosphere during photosynthesis?
a)
primary and secondary meristems
b)
xylem and phloem
c)
guard cells and stomata
d)
cambium and epidermis
2.
Which of the following best compares the processes involved in aerobic and anaerobic respiration?
a)
Glycolysis and the Krebs cycle take place in the mitochondria, while the electron transport chain takes place in the cytoplasm.
b)
Glycolysis takes place in the cytoplasm, while the Krebs cycle and electron transport chain take place in the mitochondria.
c)
The electron transport chain and glycolysis take place in the mitochondria, while the Krebs cycle takes place in the cytoplasm.
d)
The Krebs cycle and the electro transport chain take place in the cytoplasm, while glycolysis takes place in the mitochondria.
3.
Inside of an air-proof container, ethyl alcohol is being formed in yeast cells. Which of the following is the most likely conclusion one can make regarding the processes that are occurring?
a)
Carbon dioxide is also being produces as glucose moves through the electron transport chain.
b)
Fermentation is taking place as a result of a lack of oxygen.
c)
Glucose is being produces as a result of aerobic conditions.
d)
The Krebs cycle is taking place and the products will enter the mitochondria.
4.
A weightlifter is using heavy weights in short bursts for a competition. The weight lifter begins to experience fatigue. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?
a)
As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen.
b)
As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.
c)
The cells will never run out of oxygen if the weightlifter is breathing.
d)
As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP.
5.
Over the last 200 years deforestation has taken place in order to make room for an increase in the human population, farming, and industry. If this trend continues, how might the decrease in the amount of plant life on Earth effect the gas concentrations?
a)
O2 level will increase, while CO2 levels will decrease.
b)
CO2 levels in the ocean will increase, while O2 levels in the ocean will increase
c)
CO2 level will increase, while O2 levels will decrease.
d)
CO2 levels in the ocean will decrease, while O2 levels in the ocean will increase
6.
Plants need carbon and oxygen to produce glucose during photosynthesis. How do most plants obtain these elements?
a)
They take in carbon dioxide dissolved in water through the roots and transport them using xylem.
b)
The take in carbon dioxide in the air through the stomata of the leaves.
c)
They absorb carbon monoxide (CO) through respiration.
d)
They absorb carbon (C) from the soil and oxygen (O2) from the air.
7.
Which of the following correctly explains the relationship between photosynthesis and cellular respiration?
a)
The products of each process provide the reactants needed for the other.
b)
A. The products of both reactions are the same.
c)
A. The reactants for one process are the same as the reactants for the other.
d)
A. There is no relationship between photosynthesis and cellular respiration.
8.
What is the main difference between aerobic and anaerobic respiration?
a)
Aerobic uses oxygen and produces a total of 2 ATP, anaerobic does not require oxygen and produces 38 ATP molecules
b)
Aerobic respiration uses the process of glycolysis, while anaerobic does not.
c)
Aerobic uses oxygen and produces 38 ATP molecules, while anaerobic does not require oxygen and produces 2 ATP molecules
d)
Anaerobic respiration uses the process of glycolysis, while aerobic does not.
9.
What is the correct formula for photosynthesis?
a)
H2O+CO2+sunlight -> O2 + C6H12O6
b)
CO2+ sunlight + O2 -> O2 + C6H12O6
c)
O2+ C6H12O6 -> H2O + CO2 + sunlight
d)
O2+ C6H12O6 -> H2O + CO2 + ATP
10.
