Photosynthesis Quiz

What is the primary function of chlorophyll in photosynthesis?

• To produce oxygen

• To absorb sunlight

• To transport water

• To store glucose

Which of the following is a product of photosynthesis?

• ATP

• Carbon dioxide

• Glucose

• Water

What is the relationship between photosynthesis and cellular respiration?

• Both processes occur in the mitochondria

• They are unrelated processes

• Cellular respiration produces glucose used in photosynthesis

• Photosynthesis produces oxygen used in cellular respiration

In AP biology, what is the role of NADPH in photosynthesis?

• It acts as a final electron acceptor

• It absorbs sunlight

• It stores energy in the form of ATP

• It is a waste product

Where do the light-dependent reactions of photosynthesis occur?

• In the stroma

• In the thylakoid membranes

• In the cytoplasm

• In the nucleus

What is the main purpose of the Calvin cycle in photosynthesis?

• To split water molecules

• To produce oxygen

• To fix carbon dioxide into organic molecules

• To generate ATP

Which part of the leaf is responsible for gas exchange?

• Waxy cuticle

• Palisade mesophyll

• Vascular bundle

• Guard cells

What is a key difference between C3 and C4 photosynthesis?

• C4 photosynthesis occurs in the mitochondria

• C3 photosynthesis does not produce oxygen

• C4 photosynthesis involves a four-carbon compound

• C3 photosynthesis occurs at night

How do CAM plants minimize water loss?

• By using less water in photosynthesis

• By opening stomata at night

• By storing water in their leaves

• By opening stomata during the day

What is the role of rubisco in the Calvin cycle?

• It splits water molecules

• It fixes carbon dioxide to RUBP

• It generates ATP

• It absorbs sunlight
