Photosynthesis Quiz

What is the primary pigment involved in photosynthesis?

• Xanthophyll

• Carotene

• Chlorophyll

• Melanin

Where does photosynthesis take place in a plant cell?

• mitochondria

• chloroplasts

• nucleus

• cytoplasm

What are the two main stages of photosynthesis?

• Light-dependent reactions and light-independent reactions

• Dark reactions and carbon reactions

• Chlorophyll reactions and pigment reactions

• Sunlight reactions and energy reactions

What gas is taken in by plants during photosynthesis?

• Carbon dioxide (CO2)

• Nitrogen (N2)

• Hydrogen (H2)

• Oxygen (O2)

What is the primary source of energy for photosynthesis?

• Sunlight

• Nuclear energy

• Coal

• Wind power

What is the function of chlorophyll in photosynthesis?

• Store excess water for the plant

• Absorb light energy and convert it into chemical energy

• Regulate the temperature of the plant

• Reflect light energy back into the environment

What is the chemical equation for photosynthesis?

• CO2 + H2O + light energy -> CH4 + O2

• 6CO2 + 6H2O -> C6H12O6 + 6O2

• C6H12O6 + 6O2 -> 6CO2 + 6H2O + light energy

• 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2

What is the role of sunlight in photosynthesis?

• Sunlight regulates the temperature during photosynthesis.

• Sunlight provides water for photosynthesis.

• Sunlight provides the energy for the photosynthesis process.

• Sunlight releases oxygen in photosynthesis.

How do plants obtain water for photosynthesis?

• Through their leaves absorbing water from the air

• Through their stems absorbing water from sunlight

• Through their flowers absorbing water from the ground

• Through their roots absorbing water from the soil

What are the byproducts of photosynthesis?

• Glucose and oxygen

• Water and carbon dioxide

• Sunlight and soil

• Nitrogen and phosphorus
