  1. Quiz Section 4.2 Photosynthesis

  2. What is this structure? Label its parts. 5. Where is the chlorophyll found? 2 1 3 4

  3. 6. Where do the light-dependent reactions take place? • In the cytoplasm of the cell’s thylakoid membranes. • In the stroma of the chloroplast. • In the matrix of the mitochondria. • Within and across the chloroplast’s thylakoids.

  4. 7. What are the stacks of thylakoids called? • Stroma • Grana • Cytoplasm • Intramembrane matrix

  5. 8. What is the role of chlorophyll in photosynthesis? • Chlorophyll converts ultraviolet light into visible light the chloroplast can use. • Chlorophyll absorbs green light the plant can use to make carbohydrates. • Chlorophyll absorbs some light waves in the visible spectrum. • Chlorophyll provides phosphate groups to ADP to make ATP.

  6. 10. What reactant is needed in the light-independent reactions? • Oxygen • Sunlight • Carbon dioxide • Water

  7. 11. Which molecule is made during the light-dependent reactions? • Oxygen • Water • Carbon dioxide • Glucose

  8. 12. In which reactions is glucose made? • Please draw a chloroplast and label the steps, reactants, and products in the light-dependent reactions and light-independent reactions.
