Where does photosynthesis occur?
A. nucleus
B. mitochondria
C. cytoplasm
D. chloroplast
Is oxygen a reactant or a product of photosynthesis?
reactant
product
Is water a reactant or a product of photosynthesis?
reactant
product
Is carbon dioxide a reactant or a product of photosynthesis?
reactant
product
Is sunlight a reactant or a product of photosynthesis?
reactant
product
Is glucose a reactant or a product of photosynthesis?
reactant
product
What is the chemical formula of photosynthesis?
6O2 + C6H12O6 --> 6CO2 + 6H2O + sunlight
6CO2 + 6H2O + sunlight--> 6O2 + C6H12O6
6CO2+ 6O2 --> C6H12O6 + 6H2O
6CO2+C6H12O6--> 6O2+ 6H2O+ ATP
What is the primary role of photosynthesis in the carbon cycle?
A. releasing carbon to the oceans
B. remove carbon from the atmosphere
C. transferring carbon from the soil to organisms
D. transferring carbon from producers to decomposers
The diagram shows a chloroplast and some of the components of the reactions that occur in chloroplasts. Which of the following is a product of the reactions that take place in a chloroplast?
A. hydrogen gas
B. oxygen gas
C. nitrate
D. protein
Click on all of the controls of the experiment (hint there are 2)
Light Intensity
Temperature
CO2 Concentration
O2 Output Rate
What is the independent variable (what is changed by the scientist)?
Light intensity
Temperature
CO2 Concetration
O2 Output rate
What is the dependent variable (what was measured)?
Light intensity
Temperature
CO2 Concetration
O2 Output rate
What happened to the rate of oxygen output as the light intensity increased?
A. The amount of oxygen increased
B. The amount of oxygen decreased
C. The amount of oxygen stayed the same
What is the relationship between light intensity and the rate of photosynthesis?
A. the rate of photosynthesis decreases with more sunlight
B. the rate of phosynthesis increases with more sunlight
C. there is no connection

What happens to the oxygen output rate as the amount of carbon dioxide increases?
A. as carbon dioxide increases, the amount of oxygen produced increses
B. as carbon dioxide increases, the amount of oxygen produced decreases
C. there is no relationship
How might oxygen output rate be impacted in this investigation if the light intensity was kept constant at 10% instead of 40%?
