quiz photosynthesis: an overview
sandra wants to modify the diagram to include chlorophyll. which would be the most useful strategy?
a. add representations of chlorophyll molecules inside the stroma.
b. add representations of chlorophyll molecules on the outer membrane.
c. group two or more grana together, and label them as chlorophyll.
d. add an enlarged illustration of a thylakoid, and represent chlorophyll molecules in the thylakoid membrane.
(diagram of thylakoid and granum is shown)

Explanation:

Chlorophyll is located in the thylakoid membranes of chloroplasts (grana are stacks of thylakoids). Option A is wrong as chlorophyll is not in the stroma. Option B is wrong as chlorophyll is not on the outer membrane. Option C is wrong as grouping grana and labeling as chlorophyll is incorrect. Option D correctly identifies that chlorophyll is in thylakoid membranes, so adding chlorophyll representations there is the right strategy.

Answer:

D. Add an enlarged illustration of a thylakoid, and represent chlorophyll molecules in the thylakoid membrane.
