Photosynthesis and Chloroplast Function Quiz

What is the role of photosystems in photosynthesis?

• They absorb water for the plant.

• They generate and emit excited electrons.

• They store energy in the form of ATP.

• They transport nutrients to the roots.

Which molecule is regenerated in the Calvin cycle using ATP?

• NADP

• RuBP

• Glucose

• Oxygen

What is the function of thylakoids in chloroplasts?

• They store glucose.

• They contain chlorophyll for light-dependent reactions.

• They transport water throughout the plant.

• They produce carbon dioxide.

Where do the light-independent reactions of photosynthesis occur?

• In the thylakoid membrane

• In the stroma

• In the grana

• In the chlorophyll

What evidence supports the theory of endosymbiosis in chloroplasts?

• Presence of a single membrane

• Presence of circular DNA and 70S ribosomes

• Ability to perform photosynthesis

• Production of oxygen

What is the role of accessory pigments in photosystems?

• They absorb light energy and release high energy electrons.

• They store energy in the form of ATP.

• They convert carbon dioxide into organic matter.

• They produce oxygen as a by-product.

Where are photosystems located within a plant cell?

• Thylakoid membrane

• Stroma

• Cytoplasm

• Nucleus

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

• To produce glucose

• To convert light energy into chemical energy

• To release carbon dioxide

• To synthesize proteins

Which molecule is a product of the light-dependent reactions and used in the light-independent reactions?

• Oxygen

• Glucose

• NADPH

• Water

What process within the thylakoid membrane helps in ATP synthesis during the light-dependent reactions?

• Photolysis

• Chemiosmosis

• Glycolysis

• Fermentation
