Photosynthesis Quiz

What is the primary pigment involved in photosynthesis?

• Melanin

• Chlorophyll

• Carotene

• Xanthophyll

Where does photosynthesis take place in a plant cell?

• Endoplasmic reticulum

• Mitochondria

• Nucleus

• Chloroplasts

What are the two main stages of photosynthesis?

• Sunlight reactions and energy reactions

• Light-dependent reactions and light-independent reactions

• Dark reactions and carbon reactions

• Chlorophyll reactions and pigment reactions

What gas is taken in by plants during photosynthesis?

• Carbon dioxide (CO2)

• Oxygen (O2)

• Nitrogen (N2)

• Hydrogen (H2)

What is the role of chlorophyll in photosynthesis?

• Chlorophyll releases oxygen during photosynthesis.

• Chlorophyll absorbs light energy during photosynthesis.

• Chlorophyll converts carbon dioxide into glucose during photosynthesis.

• Chlorophyll provides structural support to plant cells during photosynthesis.

What is the chemical equation for photosynthesis?

• 6CO2 + 6H2O -> C6H12O6 + 6O2

• C6H12O6 + 6O2 -> 6CO2 + 6H2O

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

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

What is the purpose of the light-dependent reactions in photosynthesis?

• To regulate the temperature of the plant

• To convert light energy into chemical energy

• To produce oxygen as a byproduct

• To break down glucose molecules

How do plants obtain the water needed for photosynthesis?

• Through their leaves

• From the air

• Through their roots

• By absorbing sunlight

What is the final product of the Calvin cycle?

• sucrose

• glucose

• starch

• fructose

How does photosynthesis contribute to the oxygen cycle?

• Photosynthesis contributes to the oxygen cycle by releasing oxygen into the atmosphere.

• Photosynthesis contributes to the nitrogen cycle.

• Photosynthesis absorbs oxygen from the atmosphere.

• Photosynthesis has no impact on the oxygen cycle.
