Yasmine is asked to describe the structural organization of chloroplasts. She writes the following sentence: "A chloroplast contains thylakoid stacks, called stroma, that are surrounded by fluid-filled grana."

Which change to the sentence is necessary to make the sentence accurate?

A. Replace "grana" with "chlorophyll."
B. Replace "stroma" with "chlorophyll."
C. Exchange the positions of "stroma" and "grana."
D. Exchange the positions of "thylakoid" and "stroma."

C. Exchange the positions of "stroma" and "grana."

"A chloroplast contains thylakoid stacks, called grana, that are surrounded by fluid-filled stroma."

Explanation:

A dynamic biochemical process, photosynthesis, occurs within the chloroplasts of plants. Here, to form stable carbohydrates, light energy is transformed into chemical energy.

              6 CO2 + 6 H2O + light  →  C6H12O6 + 6 O2

Carbon Dioxide + Water + Light       Glucose + Oxygen

Chloroplasts are tiny, highly-folded, membrane-bounded organelles containing enzymes, pigments and other molecules that mediate photosynthesis. In the stack of grana,  pigments like chlorophyll, absorb light energy for the light-dependent reactions.
