Photosynthesis Quiz

What is the chemical equation for photosynthesis?

• 2H2O + 2CO2 → 2H2CO3 + O2

• 6CO2 + 6H2O + light energy → C6H12O6 + 6O2

• C6H12O6 + 6O2 → 6CO2 + 6H2O

• 4CO2 + 4H2O + light energy → C4H8O4 + 4O2

How does the photosynthesis equation contribute to the oxygen cycle?

• It contributes by releasing carbon dioxide as a byproduct.

• It contributes by reducing the amount of oxygen in the atmosphere.

• It contributes by producing oxygen as a byproduct.

• It contributes by consuming oxygen as a byproduct.

What are the factors that can affect the rate of photosynthesis in the equation?

• Wind speed, humidity, and soil nutrients

• Water concentration, oxygen concentration, and soil pH

• Leaf color, plant height, and root depth

• Light intensity, carbon dioxide concentration, and temperature

Explain the role of chlorophyll in the photosynthesis equation.

• Chlorophyll releases oxygen into the atmosphere

• Chlorophyll absorbs carbon dioxide from the air

• Chlorophyll converts water into glucose

• Chlorophyll absorbs light energy and converts it into chemical energy.
