Photosynthesis and Cellular Respiration
(Instruction) Questions and Answers
Latest Version Graded A+
What role does carbon dioxide play in photosynthesis?
✔✔Carbon dioxide is used in the Calvin cycle to produce glucose, which is the main product of
photosynthesis.
How does cellular respiration differ from photosynthesis?
✔✔Photosynthesis converts light energy into glucose and oxygen, while cellular respiration
breaks down glucose and oxygen to produce ATP, carbon dioxide, and water.
What is the primary purpose of cellular respiration?
✔✔The primary purpose of cellular respiration is to produce ATP, which provides energy for
cellular processes.
What are the three main stages of cellular respiration?
✔✔The three main stages of cellular respiration are glycolysis, the citric acid cycle, and the
electron transport chain.

,Where does glycolysis take place?
✔✔Glycolysis takes place in the cytoplasm of the cell.
What is the primary purpose of photosynthesis?
✔✔The primary purpose of photosynthesis is to convert light energy into chemical energy stored
in glucose, which plants use as food.
Where does photosynthesis occur in plant cells?
✔✔Photosynthesis occurs in the chloroplasts of plant cells, specifically in the thylakoid
membranes.
What are the main products of photosynthesis?
✔✔The main products of photosynthesis are glucose and oxygen.
What is the role of chlorophyll in photosynthesis?
✔✔Chlorophyll absorbs light energy, primarily from the sun, and uses it to power the reactions
that produce glucose in photosynthesis.
2
, What is the function of the stomata in photosynthesis?
✔✔The stomata are tiny openings on the surface of leaves that allow carbon dioxide to enter and
oxygen to exit, enabling photosynthesis to occur.
What are the two main stages of photosynthesis?
✔✔The two main stages of photosynthesis are the light-dependent reactions and the light-
independent reactions (Calvin cycle).
Where do the light-dependent reactions of photosynthesis take place?
✔✔The light-dependent reactions take place in the thylakoid membranes of the chloroplasts.
What happens during the light-dependent reactions of photosynthesis?
✔✔During the light-dependent reactions, sunlight is absorbed by chlorophyll, water molecules
are split, and ATP and NADPH are produced.
What is the purpose of the Calvin cycle in photosynthesis?
✔✔The Calvin cycle uses the ATP and NADPH produced in the light-dependent reactions to
convert carbon dioxide into glucose.
