Practice question
Question
The thylakoid system of a chloroplast is extensively damaged, but the stroma and chloroplast envelope remain intact. Which combination would be most directly affected?
Explanation
Chlorophyll occurs in the thylakoids, and stacks of thylakoids form grana, which are the sites of light reactions. Circular DNA, ribosomes and enzymes for carbohydrate and protein synthesis occur in the stroma and may remain present.
