#1
Which of the following factors primarily drives photosynthesis?
Light intensity
ExplanationHigher light intensity increases photosynthesis rate.
#2
In which organelle does photosynthesis primarily occur?
Chloroplast
ExplanationChloroplasts house the machinery for photosynthesis.
#3
What is the primary product of the light-dependent reactions of photosynthesis?
Oxygen
ExplanationOxygen is released as a byproduct of the light-dependent reactions.
#4
What pigment is responsible for capturing light energy during photosynthesis?
Chlorophyll
ExplanationChlorophyll absorbs light energy and initiates the process.
#5
What effect does an increase in carbon dioxide concentration have on photosynthesis?
Increases photosynthesis rate
ExplanationHigher CO2 levels enhance the rate of photosynthesis.
#6
What is the primary function of the Calvin cycle in photosynthesis?
To fix carbon dioxide into carbohydrates
ExplanationThe Calvin cycle converts CO2 into usable energy.
#7
Which of the following environmental conditions inhibits photosynthesis?
Low temperature
ExplanationLow temperatures slow down the photosynthesis process.
#8
Which of the following wavelengths of light is least effective in driving photosynthesis?
Green (500-600 nm)
ExplanationGreen light is poorly absorbed by chlorophyll, thus less effective.
#9
Which enzyme is responsible for carbon fixation in the Calvin cycle?
Rubisco
ExplanationRubisco catalyzes CO2 fixation in the Calvin cycle.
