Question

chlorophyll is found in compartments called ____ which are stacked into ____
thylakoids, granum
granum, thylakoids

Explanation:

In plant cell chloroplasts, chlorophyll is located in thylakoids (membrane - bound compartments). Multiple thylakoids are stacked together to form a granum. So the correct order is thylakoids (the compartments where chlorophyll is found) and then granum (the structure formed by stacking thylakoids).

Answer:

A. thylakoids, granum
