Photosynthesis Quiz

What is the name of the process where plants convert water and carbon dioxide into oxygen and glucose?

• Respiration

• Transpiration

• Photosynthesis

• Fermentation

What are the reactants of photosynthesis?

• CO₂ + H₂O

• C₆H₁₂O₆ + O₂

• CO₂ + C₆H₁₂O₆

• O₂ + H₂O

What are the products of photosynthesis?

• CO₂ + H₂O

• O₂ + H₂O

• CO₂ + C₆H₁₂O₆

• C₆H₁₂O₆ + O₂

Which reactions in photosynthesis require light?

• light-dependent reactions

• dark-dependent reactions

• light-independent reactions

• Calvin Cycle

Where do the light-dependent reactions take place?

• stroma of the chloroplasts

• nucleus

• mitochondria

• thylakoid membrane

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

• To convert liquid water into oxygen gas

• To convert light energy into chemical energy

• To convert carbon dioxide into glucose

• To perform cellular respiration

What is the primary product of the light-dependent reactions?

• Carbon dioxide

• ATP

• Glucose

• Oxygen

What is the role of water in photosynthesis?

• Water provides the electrons and hydrogen ions needed to power the light-dependent and light-independent phases of photosynthesis.

• Water absorbs light energy for photosynthesis.

• Water provides structural support to plants during photosynthesis.

• Water converts carbon dioxide into glucose.

What is the role of ATP in photosynthesis?

• ATP is responsible for the absorption of light in photosynthesis.

• ATP is used to store carbon dioxide in photosynthesis.

• ATP is a waste product in photosynthesis.

• ATP is used as an energy source.

NADP+ picks up two excited electrons and a hydrogen ion (H⁺) at the end of the light reactions to become this molecule, which helps power the dark reactions

• H₂O

• ADP

• ATP

• NADPH
