Answer
This statement is incorrect. The grana are actually the site of the light-dependent reactions, where light is absorbed and converted into energy.
Step 2
B. Chlorophyll found in the stroma traps light for use during the light-dependent stage.

Answer
This statement is also incorrect. Chlorophyll is found in the thylakoid membranes, which are part of the grana, and it captures light for the light-dependent reactions.
Step 3
C. The light-dependent stage produces ATP for use during the light-independent stage.

Answer
This statement is correct. The light-dependent reactions generate ATP and NADPH, which are then used in the light-independent reactions (Calvin cycle).
Step 4
D. The light-independent stage captures carbon dioxide for use during the light-dependent stage to produce glucose.

Answer
This statement is incorrect. The light-independent reactions do capture carbon dioxide, but they do not utilize the light-dependent reactions to produce glucose.
