Photosynthesis and Chloroplast Function Quiz

What is the role of photosystems in photosynthesis?

• They store energy in the form of glucose.

• They generate and emit excited electrons.

• They break down water molecules.

• They transport oxygen out of the cell.

Which process occurs in the thylakoids during photosynthesis?

• Carbon fixation by Rubisco

• ATP production by chemiosmosis

• Synthesis of glucose

• Regeneration of RuBP

What is the function of the stroma in chloroplasts?

• It contains chlorophyll for light-dependent reactions.

• It is the site of light-independent reactions.

• It stores oxygen produced during photosynthesis.

• It transports electrons between photosystems.

What evidence supports the theory of endosymbiosis in chloroplasts?

• Presence of chlorophyll

• Double membrane structure

• Production of glucose

• Presence of thylakoids

What is the role of grana in chloroplasts?

• They connect thylakoid stacks.

• They increase surface area to volume ratio for light absorption.

• They store enzymes for the Calvin cycle.

• They transport ATP and NADPH.

What is the main function of photosystems in photosynthetic organisms?
