Photosynthesis and Chloroplast Function Quiz

What is the primary function of photosystems in photosynthesis?

• To absorb water

• To generate and emit excited electrons

• To produce glucose

• To break down chlorophyll

Which structure in the chloroplast is responsible for the light-dependent reactions?

• Stroma

• Grana

• Thylakoids

• Lamella

What is the role of the stroma in the chloroplast?

• Site of light-dependent reactions

• Contains chlorophyll

• Location of light-independent reactions

• Connects thylakoid stacks

What evidence supports the theory of endosymbiosis in chloroplasts?

• Presence of chlorophyll

• Double membrane structure

• Production of oxygen

• Synthesis of glucose

What is the function of grana in the chloroplast?

• Contains enzymes for the Calvin cycle

• Increases surface area to volume ratio for light absorption

• Connects thylakoid stacks

• Stores genetic material

What is the role of the thylakoid membrane in photosynthesis?

• It absorbs carbon dioxide.

• It houses photosystems for light absorption.

• It stores glucose.

• It releases oxygen directly.

Which molecule is produced during the light-dependent reactions of photosynthesis?

• Glucose

• Oxygen

• ATP

• Carbon dioxide

What is the function of Photosystem II in the light-dependent reactions?

• It absorbs carbon dioxide.

• It splits water molecules.

• It synthesizes glucose.

• It stores energy in NADPH.

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

• To produce oxygen

• To convert light energy into chemical energy

• To synthesize organic compounds

• To release hydrogen gas

How are the light-dependent and light-independent reactions of photosynthesis related?

• They occur in the same location.

• They are independent of each other.

• The products of the light-dependent reactions are used in the light-independent reactions.

• They both produce ATP.
